1 is a block diagram of a user terminal device according to an embodiment of the present invention.

Referring to FIG. 1, a user terminal device 100 according to an embodiment of the present invention may include a client hypervisor 110, a first user module 120, and a second user module 130. . Herein, the first user module 120 and the second user module 130 may be arbitrarily exemplified in number for convenience of description, and may further include third to Nth user modules.

The client hypervisor unit 110 corresponds to a virtual platform for simultaneously executing a plurality of operating systems (OSs), and serves as a main OS in the user terminal device 100, and the client hypervisor unit A plurality of virtual machines operating on 110 serve as a guest OS.

The client hypervisor 110 in the present embodiment may include a virtual machine switching unit 111. The virtual machine switching unit 111 switches usage rights of resources granted to the plurality of virtual machines. Here, the right to use a resource allows each virtual machine to use physical hardware, and includes an input / output control right. That is, the virtual machine switching unit 111 may grant or recover the use right of the resource to at least one virtual machine among the plurality of virtual machines, and the right to use the resource may or may not include the input / output control right as necessary. It may not.

When the client hypervisor 110 requests a switch from the virtual machine # 1 121 or the virtual machine # 2 131 to another virtual machine, the client hypervisor 110 sends a resource to the switching target virtual machine through the virtual machine switching unit 111. Grant permission.

The first user module 120 may include a virtual machine # 1 121, an operating system # 1 122, an application A 123, an application B 124, and a link manager # 1 125. In addition, the second user module 130 may include a virtual machine # 2 131, an operating system # 2 132, an application C 133, an application D 134, an application E 135, and a link manager # 1 125. ) May be included.

At least one virtual machine is installed on the client hypervisor 110, and each operating system is installed on the virtual machine. In addition, at least one application may be installed on each operating system. As described above, the virtual machine, the operating system, and the applications are sequentially installed on the client hypervisor 110. Accordingly, in the present embodiment, these are called user modules.

As shown, in the present embodiment, two virtual machines on the client hypervisor unit 110, namely, virtual machine # 1 121, operating system # 1 122, virtual machine # 2 131, and operating system # 2. 132, two applications, that is, application A 123 and application B 124, are installed in OS # 1 122, and three applications, that is, application C 133, in OS # 2 132. And the application D 134 and the application E 135 are illustrated.

In addition, the link manager may be further installed on the operating system. The link manager may provide a list of at least one application respectively installed on the plurality of virtual machines and request execution of the selected application through the application list, and may be installed on the operating system in the form of a single application. In the present embodiment, it is illustrated that the link manager # 1 125 is installed on the operating system # 1 122, and the link manager # 2 136 is installed on the operating system # 2 132. However, the link management unit # 1 125 and the link management unit # 2 136 are different from each other, but perform the same function in terms of their functions.

The link manager # 1 125 and the link manager # 2 136 must synchronize application information on a user module to which the counterpart belongs in order to provide an application list for applications installed in all virtual machines on the client hypervisor 110. do. There are two ways to synchronize information about an application.

First, there may be a case in which one of the user modules always operates to obtain and retain information on an application on another user module. If the first user module 120 is set to operate at all times, the link manager # 1 125 may change the application included in the second user module 130. That is, the application is installed or deleted. If so, application information is retrieved from the link management unit # 2 (136).

Second, when at least two of the user modules are operating, there may be a case where the operating user modules synchronize application information with each other. If both the first user module 120 and the second user module 130 are operating, the first user module 120 receives the application information of the second user module 130 from the second user module 130. The second user module 130 imports application information of the first user module 120 from the first user module 120.

By the above method, upon receiving a request for providing a list of applications from a user, the link manager # 1 125 or the link manager # 2 136 stores the application information of the user module to which the user belongs and the applications of other user modules. The information can provide a list of applications. Here, the application list may be provided in a form in which a user may select an application to be executed.

Hereinafter, the operation of the link manager will be described by taking an example in which a specific application is selected through the link manager # 1 from the user. First, the application selected by the user may be included in a user module such as the link management unit # 1, and may be an application included in another user module (for example, the user module 130). Let's do it.

In the first case, that is, the application selected by the user is included in the user module # 1 120 such as the link manager # 1, the link manager # 1 may immediately execute the application selected by the user. Of course, in this case, it is assumed that the virtual machine # 1 has been allocated with sufficient resources for the user-selected application to operate. If not enough resources are allocated, the user module 120 provides sufficient resources to the client hypervisor. You will be asked to assign one.

In the second case, i.e., when the application selected by the user is included in the user module # 2 (for example, when the application C 133 is selected), the link manager # 1 125 may inform the client hypervisor 110. The user requests the execution of the selected application C 133. The client hypervisor 110 performs an operation for executing the application C 133 according to a request of the link manager # 1 125. Specifically, the client hypervisor 110, if a resource has already been allocated to the user module # 2 to which the application C (133) belongs, immediately requests to execute the application C (133) to the link management unit # 2, if the user module If sufficient resources are not allocated to the application C 133 in operation # 2, the virtual machine switching unit 111 requests resource allocation from the user module # 2. Subsequently, when resource allocation is made to the user module # 2, the link management unit # 2 requests the execution of the application C 133.

2 is a block diagram of a user terminal device according to another embodiment of the present invention.

2, a user terminal device 100 according to another embodiment of the present invention may include a client hypervisor 110, a first user module 120, and a second user module 130. . That is, the user terminal device 100 according to the present embodiment has a configuration similar to that of the user terminal device 100 shown in FIG. 1. Accordingly, the same reference numerals are used to designate the same components, and the description of the same components will be omitted and only different configurations will be described.

The client hypervisor unit 110 may include a virtual machine switching unit 111 and an application manager 112. The application manager 112 has some functions of the link manager shown in FIG. 1 and is included in the client hypervisor 110. The configuration in which the application manager 112 is included in the client hypervisor 110 is advantageous in that the application manager 112 may continue to operate while the user terminal device 100 operates. Meanwhile, the virtual machine switching unit 111 may allocate a resource to the virtual machine and activate the virtual machine when a request for switching of the virtual machine is received from the application manager 112.

The application manager 112 includes information on all the applications of the user modules, and provides a list of all applications to the user module on request or periodically or aperiodically.

That is, when a request for providing an application list is received from the first user module 120 or the second user module 130, all the user modules included in all the user modules on the client hypervisor 110 are stored by the existing application information. The application list including information on the application is provided to the user module requesting to provide the application list.

In addition, when the application management unit 112 receives a request for executing an application included in the second user module from the first user module 120, the application manager 112 makes a target application execution request to the link unit # 2 136. When the execution request of an application included in the first user module is received from the user module 130, the target application execution request may be made to the link unit # 1 126.

When a change of an application in the user module occurs, the change may be notified to the client hypervisor 110.

The first user module 120 may include a virtual machine # 1 121, an operating system # 1 122, an application A 123, an application B 124, and an application A 123 and an application B 124. Link portion # 1 125 may be included on the same level as the.

The link unit provides the user with a list of applications that the user has when the virtual machine of the user module to which the user module belongs is operating with the permission of the resource. Alternatively, an application list request may be made to the application manager 112, and the application list may be provided to the user by receiving the application list from the application manager 112.

Hereinafter, the operation of the link unit will be described by taking an example in which a specific application is selected through the link unit # 1 from the user. First, the application selected by the user may be included in a user module such as the link unit # 1, and may be an application included in another user module (for example, the user module 130). Let's do it.

In the first case, that is, when the application selected by the user is included in the user module # 1 such as the link unit # 1, the link unit # 1 may immediately execute the application selected by the user. Of course, in this case, it is assumed that the virtual machine # 1 has been allocated with sufficient resources for the user-selected application to operate. If not enough resources are allocated, the user module 120 provides sufficient resources to the client hypervisor. You will be asked to assign one.

In the second case, i.e., when the application selected by the user is included in the user module # 2 (for example, when the application C 133 is selected), the link unit # 1 125 transmits the user to the application manager 112. Requests execution of the selected application C (133). The application manager 112 performs an operation for executing the application C 133 according to the request of the link unit # 1 125. Specifically, the application manager 112, if a resource has already been allocated to the user module # 2 to which the application C (133) belongs, immediately requests to execute the application C (133) to the link unit # 2, if the user module # If sufficient resources are not allocated to the application C 133 to operate in step 2, the virtual machine switching unit 111 requests resource allocation from the user module # 2. Thereafter, when resource allocation is made to the user module # 2, the link unit # 2 is requested to execute the application C 133.

In the present embodiment, it is illustrated that the application manager 112 is included in the client hypervisor 110, and the link unit is installed on each operating system. That is, the function of the link manager shown in FIG. 1 is divided into an application manager 112 and a link unit.

3 is a block diagram of a user terminal device according to another embodiment of the present invention.

Referring to FIG. 3, the user terminal device 100 according to another embodiment of the present invention may include a client hypervisor 110, a first user module 120, a second user module 130, and a management module ( 140). Since the user terminal apparatus 100 according to the present exemplary embodiment has a similar configuration to that of the user terminal apparatus 100 illustrated in FIG. 2, the same reference numerals are used to designate the same components, and descriptions of the same components are omitted. Only the configurations that differ.

The client hypervisor unit 110 includes a virtual machine switching unit 111 as shown in FIG. The first user module 120 and the second user module 130 are installed on the client hypervisor 110. In the present embodiment, the first user module 120 and the second user module 130 are at the same level as the first user module 120 and the second user module 130. The management module 140 may be further installed on the top.

The management module 140 may include a management virtual machine 141, a management operating system 142, and an application manager 143. The management virtual machine 141 is installed at the same level as the virtual machine # 1 121 and the virtual machine # 2 131 on the client hypervisor 110. Also, the management operating system 142 is installed on the management virtual machine 141 on the same level as the operating system # 1 122 and the operating system # 2 132.

The application manager 143 may be installed on the management operating system 142. The application manager 143 performs the same function as the application manager 112 in the client hypervisor 110 shown in FIG. 2, except that the installation location is different. As mentioned in the previous embodiment, the application unit manager 143 may be implemented as a single application that performs a corresponding function.

The management module 140 is a module configured to operate in the background when the client hypervisor 110 starts to operate. When a change occurs in an application in the user module installed on the client hypervisor 110, This change is notified through the client hypervisor 110. As a result, the application manager 143 included in the management module 140 may always have the latest application information.

That is, the application manager 143 may include information about all applications of the user modules, and may provide a list of all applications to the link units of the user modules on request or periodically or aperiodically. .

The operation of the link unit will be described by taking an example in which a specific application is selected through the link unit # 1 from the user. As in the embodiment of FIG. 2, the application selected by the user may be included in a user module such as the link unit # 1, or may be an application included in another user module (for example, the user module 130). Each will be described sequentially.

In the first case, that is, when the application selected by the user is included in the user module # 1 such as the link unit # 1, the link unit # 1 may immediately execute the application selected by the user. Of course, in this case, it is assumed that the virtual machine # 1 has been allocated with sufficient resources for the user-selected application to operate. If not enough resources are allocated, the user module 120 provides sufficient resources to the client hypervisor. You can ask to assign.

In the second case, i.e., when the application selected by the user is included in the user module # 2 (for example, when the application C 133 is selected), the link unit # 1 125 sends an application manager 143 to the user. Requests execution of the selected application C (133). The application manager 143 performs an operation for executing the application C 133 according to the request of the link unit # 1 125. In detail, if a resource is already allocated to the user module # 2 to which the application C 133 belongs, the application manager 143 requests to execute the application C 133 to the link unit # 2 immediately. If sufficient resources are not allocated to the application C 133 to operate in step 2, the virtual machine switching unit 111 requests resource allocation from the user module # 2. Thereafter, when resource allocation is made to the user module # 2, the link unit # 2 is requested to execute the application C 133.

On the other hand, the second case described above can be modified as follows. For example, when the application selected by the user is included in the user module # 2 (for example, when the application C 133 is selected), the link unit # 1 125 is the client hypervisor unit, and the application C 133 may be installed. After the execution request, the client hypervisor determines whether sufficient resources are allocated to the user module # 2 and requests the link unit # 2 136 to execute the application C 133 selected by the user. If sufficient resources are not allocated to the user module # 2, after allocating sufficient resources to the user module # 2, the link unit # 2 136 requests the execution of the application C 133.

4 is a block diagram of a user terminal device according to another embodiment of the present invention.

Referring to FIG. 4, the user terminal device 100 according to another exemplary embodiment of the present invention may include a client hypervisor 110, a master user module 150, and a plurality of slave user modules, that is, a first slave user. The module 160 and the second slave user module 170 may be included.

The client hypervisor unit 110 includes a virtual machine switching unit 111 and has the same structure as in the embodiment illustrated in FIGS. 1 and 3. Accordingly, these reference numerals are denoted the same as in the previous example.

The master user module 150 may include a master virtual machine 151, a master operating system 152, an application F 153, an application G 154, and a link unit # 3 155. When the client hypervisor unit 110 is operated, the client hypervisor unit 110 grants a use right of a resource to the master virtual machine 151, so that the master user module 150 is always maintained. In this case, the use right of the resource granted to the master virtual machine 151 may be the use right of the resource except the input / output control right so that the master user module 150 operates in the background.

In this embodiment, the master user module 150 includes the functions of the application manager 112 described in the previous embodiment. That is, the master user module 150 provides a list of applications, and when a user requests execution of a specific application, the master user module 150 requests the client hypervisor 110 to switch to a slave virtual machine to which the previously requested application belongs. For example, the link unit # 3 155 of the master user module 150 may transmit the application list when there is a request from other link units or periodically or aperiodically.

The link unit # 3 155 may be installed on the same level as the application F 153 and the application G 154 on the master operating system 152 on the master virtual machine 151. The link unit # 3 155 may receive a request for executing an application while providing a resource list, and may provide a list of applications, and may provide a list of applications to the user. A selection signal of an application to be executed may be input from the application list.

The link unit # 3 155 according to the present exemplary embodiment may include all the functions of the application manager in FIG. 3. Accordingly, the link unit # 3 155 may transmit the application list periodically or aperiodically to the link units belonging to other user modules, or when there is a request from such link units. The application list included in the link unit # 3 155 may be received from the client hypervisor unit.

In addition, the link unit # 3 155 may provide a list of applications to the user and receive a selection signal of a specific application from the user. If the user selects the application F, the link unit # 3 155 may execute the application F immediately. However, if the user selects an application included in another user module such as application H, the link unit # 3 155 may request execution of the application H from the client hypervisor unit. In this case, if the resource is allocated to the user module 160, the client hypervisor unit requests the execution of the application H to the link unit # 4, but if the resource is not allocated to the user module 160, the virtual machine switching After the unit 111 allocates a resource to the user module 160, it requests the link unit # 4 to execute the application H.

On the other hand, the link unit # 3 (155) when the execution request for any one of the application F (153) and the application G (154) from the client hypervisor 110, may execute the application requested to be executed.

The first slave user module 160 may include a slave virtual machine # 1 161, a slave operating system # 1 162, an application H 163, an application I 164, and a link unit # 4 165. have.

The second slave user module 170 may include the slave virtual machine # 2 171, the slave operating system # 2 172, the application J 173, the application K 174, the application L 175, and the link unit # 5 176. ) May be included.

In the present embodiment, the applications F to L (153 to 155, 163 and 164, 173 to 175) included in the master user module 150 and the first and second slave user modules 160 and 170 are assigned to respective applications. The names of the user modules included are only for distinguishing and may be the same applications as the applications A to E 123, 124, 133, 134, and 135 in the previous embodiment.

In addition, the link units # 3 to # 5 (155, 165, 176) are also included in the master user module 150 and the first and second slave user modules 160 and 170, respectively. Only for the purpose of distinguishing the user module from the actual operation may be the same.

However, since the link unit # 3 155 is included in the master user module 150, when a change occurs in each application from the first and second slave user modules 160 and 170, it is notified of this. Can be. That is, the link unit # 3 155 may always maintain the latest information on the applications in the first and second slave user modules 160 and 170.

The operation of the link unit will be described by taking an example in which a specific application is selected through the link unit # 4 from the user. Similar to the embodiment of FIG. 3, the application selected by the user is an application included in another user module (for example, the user module 170 or 150), as in the case of being included in a user module such as the link unit # 4. Since there are cases, each of them will be described sequentially.

In the first case, that is, the application selected by the user is included in the user module 160 such as the link unit # 4, the link unit # 4 may immediately execute the application selected by the user. Of course, in this case, it is assumed that the slave virtual machine # 1 has been allocated enough resources for the user-selected application to operate. If not enough resources are allocated, the user module 160 is sufficient to provide the client hypervisor. You can request to allocate resources.

In the second case, that is, the application selected by the user is included in the user module 170 (for example, when the application J is selected), the link unit # 4 165 may be the link unit # 3 155. Requests execution of the selected application J 173. The link unit # 3 155 performs an operation for executing the application J 173 according to the request of the link unit # 4 165. In detail, the link unit # 3 155 may request the client hypervisor to execute the application J 173. The client hypervisor unit may request execution of the application J 173 to the link unit # 5 176 by such a request. At this time, the client hypervisor checks in advance whether the resource is allocated to the slave virtual machine # 2. If the resource is not allocated, the client hypervisor unit allocates the resource to the slave virtual machine # 2. ) Can be requested.

On the other hand, in the variation of the second case, for example, when the user-selected application is included in the user module 170 (for example, when the application J (173) is selected), the link unit # 4 (125) is the client The hypervisor unit requests execution of the application J 173, and the client hypervisor unit confirms that sufficient resources are allocated to the slave virtual machine # 2, and then executes the application J 173 selected by the user with the link unit # 5 176. Ask. If the resource is not allocated to the slave virtual machine # 2, the client hypervisor unit allocates the resource to the slave virtual machine # 2 and requests the link unit # 5 176 to execute the application J 173.

The master user module 150 described above operates in the concept of a master with respect to the slave user module, but may also include a function corresponding to the general user module in the previous embodiment.

1 to 4, each component is shown as being included in one functional block, but this is for convenience of description and does not necessarily mean that it is implemented in one apparatus. Therefore, the present invention is not limited only to such a configuration, and for example, at least one or more of these components may be implemented as separate functional blocks. Here, the term "separate" means to include logically divided, positionally divided, or different software or hardware.

5 is a flowchart illustrating a method for switching a multi virtual machine of a user terminal device according to an exemplary embodiment of the present invention.

Here, as shown in FIG. 1, a method of switching a multi-virtual machine in the user terminal device 100 having a structure in which each link management unit is included in each user module will be described.

When the virtual machine # 1 121 is granted permission to use a resource by the user's selection, or when the virtual machine # 1 121 is set to always operate by default, the client hypervisor 110 110 switches the virtual machine. Authorization of the resource is given to the virtual machine # 1 121 through the unit 111. As a result, when the virtual machine # 1 121 operates, the operating system # 1 122 and the link manager # 1 125 operate (S201). The operating system is operated on the virtual machine when a resource is given permission to use the virtual machine. In the present embodiment, the operating system is not shown for convenience of description.

The link manager # 1 125 provides a list of applications based on previously held application information (S203). In this case, the link manager # 1 125 may be in a state of receiving an application list request from the user. In addition, the application list provided by the link manager # 1 125 is a list of applications in all user modules installed on the client hypervisor 110 including the user module to which the link manager # 1 125 belongs. In addition, it may be provided in a form in which the user can select at least one of the plurality of applications displayed in the application list.

In operation S203, the link manager # 1 125 provides a list of applications, and receives a request for executing an application on another virtual machine from the user (S205). As a result, the link manager # 1 125 requests the client hypervisor 110 to switch to the virtual machine to be switched (S207).

The client hypervisor 110, which is requested to switch to the switch target virtual machine from the link manager # 1 125, checks the operation state of the switch target virtual machine (S209). Here, the operation state of the switch target virtual machine may be to check whether or not to use the resources donated to the switch target virtual machine.

The client hypervisor 110 controls the virtual machine switching unit 111 to grant the I / O control right to the virtual machine # 2 131 when the switching target virtual machine is operating (S211-Y). ). The reason for this is that, if the virtual machine to be switched is operating, the authority to use the resource is already granted, but the input / output control right is not obtained.

The client hypervisor 110 instructs execution of the application requested to be executed by the link manager # 2 136 through the virtual machine # 2 131 (S215). Here, steps S213 and S215 are illustrated as being sequentially performed with each other, but in some cases, the two steps may be simultaneously performed.

As a result, the link manager # 2 136 executes the corresponding application (S217). The application executed in step S217 may be at least one of the applications C to E (133 to 135).

In operation S211, when the switching target virtual machine is not in an operating state (S211-N), the client hypervisor 110 controls the virtual machine switching unit 111 to include an input / output control right in the virtual machine # 2 131. The right to use the resource is granted (S219). As a result, the second user module 130, that is, the virtual machine # 2 131, the operating system # 2 132, and the link manager # 2 136 are operated.

The client hypervisor 110 instructs the link management unit # 2 136 to execute the application requested to be executed through the virtual machine # 2 131 (S221), and the link manager # 2 136 executes the application. (S223). The application executed in step S223 may be at least one of the applications C to E (133 to 135).

In the above-described embodiment, the user is described as receiving an application execution request on another virtual machine. However, there may be a case where the application execution on the virtual machine to which the link manager # 1 125 belongs. In this case, the link manager # 1 125 may immediately execute the application requested by the user.

6 is a flowchart illustrating a method for switching a multi virtual machine of a user terminal device according to another exemplary embodiment of the present invention.

Here, as shown in FIG. 2, the application management unit 112 and the link unit exist separately, but when the application management unit 112 is included in the client hypervisor unit 110 will be described a multi-virtual machine switching method. do.

It is assumed that the user requests the operation of the first user module 120. The client hypervisor 110 grants permission to use the resource to the virtual machine # 1 121 by the virtual machine switching unit 111 (S301). As a result, the virtual machine # 1 121, the operating system # 1 122, and the link unit # 1 125 are operated (S303).

The link unit # 1 125 receives an application list display request from the user (S305), and requests the application list from the application manager 112 (S307). As a result, the application manager 112 provides an application list in a form that can be selected by existing application information (S309).

The link unit # 1 125 provided with the application list from the application manager 112 displays the application list (S311), and receives a request for execution of a specific application from the user through the application list (S313).

When the link unit # 1 125 receives an application execution request from the user, the link unit # 1 125 requests the application manager 112 to execute the requested application (S315).

The application manager 112, which receives the execution request for the specific application from the link unit # 1 125, requests the client hypervisor 110 to switch to the switch target virtual machine including the previously requested application ( S317).

The client hypervisor 110, which is requested to switch to the switch target virtual machine from the application manager 112, checks the operation state of the switch target virtual machine (S319).

The client hypervisor 110 controls the virtual machine switching unit 111 to grant an input / output control right to the virtual machine # 2 131 when the switching target virtual machine is operating (S321-Y) (S323). ). The client hypervisor 110 instructs execution of the application requested to be executed by the link unit # 2 136 through the virtual machine # 2 131 (S325). As a result, the link unit # 2 136 executes the corresponding application (S327).

In operation S321, when the switching target virtual machine is not in an operating state (S321 -N), the client hypervisor 110 controls the virtual machine switching unit 111 to include an input / output control right in the virtual machine # 2 131. The right to use the resource is granted (S329). The client hypervisor 110 instructs the execution of the application requested to be executed by the link unit # 2 136 through the virtual machine # 2 131 (S331), and the link unit # 2 136 executes the corresponding application. (S333).

In step S307 and step S315, the request of the link unit # 1 125 is transferred to the application manager 112 through the client hypervisor 110, and the application manager 112 is included in the client hypervisor 110. This is because the configuration example is illustrated. If the application manager 112 is included in the management module 140 as shown in FIG. 3, the request of the link unit # 1 125 in the steps S307 and S315 is performed by the client hypervisor 110. The virtual machine 141 and the management operating system 142 will be delivered to the application manager 112.

Even when the user terminal device 100 is configured as shown in FIG. 3, the switching of the multi-virtual machine may be performed by the above-described procedure. However, when the configuration of the user terminal device 100 is the same as that of FIG. 3, the client hypervisor 110 and the management virtual machine are configured to transmit signals between the application manager 112 and the first and second user modules 120 and 130. 141, and management operating system 142 will be further interposed. Here, the presence of the client hypervisor 110, the management virtual machine 141, and the management operating system 142 does not mean that they directly participate in the transmission of the signal, but means that it serves as a path for signal transmission.

In the above-described embodiment, the application manager 112 has been described as transmitting when the virtual machine # 1 requests the application list, but this is exemplary, and the application manager 112 voluntarily periodically and aperiodically the virtual machine # 1. It may also be possible to configure it to send

In addition, in the above-described embodiment, step S323 has been described that grants the input and output control right to the virtual machine # 2, which is an example, it will be understood to grant all the resources necessary to run the application.

7 is a flowchart illustrating a method for switching a multi virtual machine of a user terminal device according to another embodiment of the present invention.

Here, as shown in FIG. 4, a multi-virtual machine switching method will be described when the user terminal device 100 includes a master user module 150 and a plurality of slave user modules.

Assume that the user has requested execution of the slave virtual machine # 1 161. The client hypervisor unit 110 basically grants permission to use the resource to the master virtual machine 151, and grants permission to use the resource to the slave virtual machine # 1 161 requested by the user (S401). For example, the client hypervisor 110 may grant the master virtual machine 151 permission to use resources excluding the input / output control right so that the master virtual machine 151 operates in the background, and the slave virtual machine # 1 161 operates in the main. Authority to use resources including I / O control can be granted.

In operation S401, the slave virtual machine # 1 161, the slave operating system # 1 162, and the link unit # 4 165 are operated (S403). Although not shown, the master virtual machine 151, the master operating system 152, and the link unit # 3 155 are also operating.

The link unit # 4 165 receives an application list display request from a user (S405), and the master virtual machine 151 provides an application list by using information of an existing application (S409).

The link unit # 4 165 displays an application list provided from the master virtual machine 151 (S411), and receives an execution request of a specific application through the application list (S413). As a result, the link unit # 4 165 requests the master virtual machine 151 to execute the specific application requested to be executed by the user (S415).

The master virtual machine 151 receiving the execution request for the specific application from the link unit # 4 165 requests the client hypervisor 110 to switch to the switch target virtual machine including the previously requested application. (S417).

The client hypervisor 110, which is requested to switch from the master virtual machine 151 to the switch target virtual machine, checks the operation state of the switch target virtual machine (S419).

When the switching target virtual machine is operating (S421-Y), the client hypervisor unit 110 controls the virtual machine switching unit 111 to grant an input / output control right to the slave virtual machine # 2 171 ( S423). The client hypervisor 110 instructs execution of the application requested to be executed by the link unit # 5 176 through the slave virtual machine # 2 171 (S425). As a result, the link unit # 5 176 executes the corresponding application (S427).

In operation S421, when the switching target virtual machine is not in an operating state (S421 -N), the client hypervisor 110 controls the virtual machine switching unit 111 to give an I / O control right to the slave virtual machine # 2 171. The right to use the resource is included (S429). The client hypervisor 110 instructs the execution of the application requested to be executed by the link unit # 5 176 through the slave virtual machine # 2 171 (S431), and the link unit # 5 176 executes the corresponding application. To execute (S433).

In the above-described embodiment, the link unit # 3 has been described as being transmitted when the link unit # 4 requests the application list. However, this is an example, and the link unit # 3 voluntarily periodically and aperiodically transmits it to the virtual machine # 4. It may be possible to configure the system to In addition, in the above-described embodiment, the step S423 has been described that grants the I / O control right to the slave virtual machine # 2, which is an example, it will be understood to grant all the resources necessary to run the application.

As described above, the user terminal device 100 having the configuration illustrated in FIGS. 1 to 4 may switch multiple virtual machines by various procedures as illustrated in FIGS. 5 to 7. Although various methods are provided in the procedure as shown in FIGS. 5 to 7, the user can switch the virtual machine and execute the application by a simple operation of selecting at least one application to be executed from the application list. As it is, it can provide convenience in use.

Although the present invention as described above has been described by way of limited embodiments and drawings, the present invention is not limited to the above embodiments, and those skilled in the art to which the present invention pertains various modifications and variations from this description.
