Description

  The present invention relates to an information processing system, and more particularly to an information processing system capable of providing a plurality of virtual computers.

  2. Description of the Related Art A shared virtual PC thin client system is used that constructs a plurality of virtual PCs on a virtual PC (Personal Computer) server and provides the virtual PCs so that they can be simultaneously connected to a plurality of users. In such a thin client system, a personal environment (user profile) is applied when a user logs in to a guest OS (Operating System) operating on a virtual PC. Specifically, the connection broker equipped in the thin client system collectively sets and manages which user can use which virtual PC from which terminal.

  Here, the user profile is copied from the file server to the guest OS when logging into the guest OS. For this reason, when many users log in at one time (login storm), for example, at the start time of a company, a large number of user profile copies are generated. Then, the CPU (Central Processing Unit) of the virtual PC server, the network load, and the storage I / O (Input / Output) increase, which may cause problems such as login delay / impossibility.

  On the other hand, the technique of Patent Document 1 has been proposed for problems such as an increase in storage I / O for the specific time period. In Patent Document 1, in a storage device, a data access status is monitored, and a time when reading / writing is expected is scheduled and stored in a cache memory in advance. Thus, it has been proposed to reduce the load caused by data access.

  However, the method using the schedule as described above requires a certain amount of time for learning for creating a schedule, and the load reduction during that time is not performed. In addition, since the trigger of login / logout depends on the use of the user, no effect can be expected even when login / logout is not performed as scheduled.

  As a method for reducing the load caused by copying a user profile, a technique disclosed in Patent Document 2 has been proposed. In Patent Document 2, application termination and user profile saving are performed when a user logs out, and pseudo logout is performed to lock the user operation and the screen while maintaining the login session. Then, at the next login time of the user who has logged out pseudo, by assigning the virtual PC that was logged out last time, the user profile is not copied, and the load is reduced.

JP2015-141545A JP 2014-191402 A

  Here, a user (another user) other than the pseudo-logout user may be assigned to the virtual PC that has undergone the pseudo-logout. In this case, a normal logout (actual logout) is performed by the guest OS function in the virtual PC that has been pseudo-logged out, and another user is logged in.

  However, if the pseudo logout is continued in the virtual PC, the system resources of the virtual PC server remain in use. At this time, there is no particular problem if there is a free system resource, and the load on the virtual PC server can be reduced as described above. However, when there is no free system resource, there arises a problem that the load on the virtual PC server increases.

  Therefore, an object of the present invention is to solve the above-described problem that the load of a server that provides a virtual computer increases.

<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram for explaining the configuration of the information processing system, and FIGS. 2 to 3 are diagrams for explaining the operation of the information processing system.

[Constitution]
As illustrated in FIG. 1, the information processing system according to the present embodiment includes a virtual PC server 10, a connection broker 20, a virtual environment management server 30, and a user terminal 40 connected via a network. Yes.

  The user terminal 40 is an information processing apparatus operated by a user, and is a terminal used to connect to the virtual PC 110 provided by the virtual PC server 10. User terminals 40 are prepared for each user, and a plurality of user terminals 40 can be connected to the virtual PC server 10 at the same time.

  The virtual PC server 10 (server device) is a server device including an arithmetic device and a storage device, and a plurality of virtual PC servers 10 (server devices) are provided. The virtual PC server 10 constructs a virtual PC 110 (virtual computer) when the equipped arithmetic device executes a program. The virtual PC server 10 is connected via a network and provides the user terminal 40 that has logged in by incorporating the user profile (personal environment) of the user into the virtual PC 110. That is, the virtual PC server 10 has a function as a thin client system that provides the virtual PC 110 so that it can be simultaneously connected to a plurality of users.

  The virtual PC 110 includes a guest OS 111 and various applications that operate on the virtual PC 110, and is operated by the logged-in user terminal 40. The virtual PC 110 includes a pseudo logout processing unit 112 (pseudo logout execution unit) that detects a logout request from the user terminal and performs pseudo logout. Specifically, when the pseudo logout processing unit 112 detects a logout request to the OS from the user terminal 40, the pseudo logout processing unit 112 locks the operation from the user terminal 40 while maintaining the user profile incorporated in the virtual PC 110. The pseudo logout state is set. Therefore, the virtual PC 110 in the pseudo logout state can provide the same virtual PC 110 as it is when there is a login request from the same user terminal 40 later.

  In addition, regarding the implementation of pseudo logout, re-login, and the like, since the technique disclosed in Patent Document 2 can be used, detailed description thereof is omitted.

  The connection broker 20 (control device, control unit) is an information processing device that includes an arithmetic device and a storage device. The connection broker 20 includes a login request processing unit 21, an allocation unit 22, a logout execution unit 23, and a logout determination unit 24, which are constructed when the equipped arithmetic device executes a program.

  The login request processing unit 21 receives a login request from the user terminal 40 and confirms whether the user is in a pseudo logout state in any of the virtual PCs 110. Then, the confirmation result is notified to the assignment unit 22, and the assignment unit 22 assigns an appropriate virtual PC to the user terminal 40. For example, when the user terminal 40 is not in the pseudo logout state, a virtual PC 110 incorporating the user profile of the user is newly constructed and assigned. When the user terminal 40 is in the pseudo logout state, the virtual PC 110 that already holds the user profile of the user is assigned.

  The logout execution unit 23 performs actual logout for sequentially releasing the incorporated user profiles to the virtual PC 110 that is in a pseudo logout state at an arbitrary time zone. At this time, the logout execution unit 23 requests the logout determination unit 24 to determine whether or not the actual logout may be performed. The logout execution unit 23 performs the actual logout of the virtual PC 110 when the logout determination unit 24 permits the actual logout, and does not perform the actual logout when the actual logout is rejected. Continue the pseudo logout state.

  When the logout determination unit 24 receives a request for determining whether or not the actual logout is possible from the logout execution unit 23, the logout determination unit 24 determines whether or not the actual logout may be performed according to the operation status of the virtual PC 110, and the determination result is output to the logout execution unit. Return to 23. In this embodiment, the logout determination unit 24 checks the usage status of system resources such as CPU and memory mounted on the virtual PC server 10 as the operating status of the virtual PC 110, and implements the actual logant according to the usage status. It is determined whether or not to do so.

  Specifically, the logout determination unit 24 first checks whether the usage rate of the system lease is equal to or greater than a threshold value. This threshold value is a preset value that serves as a reference for determining whether or not there is a margin in system resources. Then, when the usage rate of the system resource is equal to or greater than the threshold, the logout determination unit 24 determines that there is no room in the system resource and determines that the actual logout may be performed (actual logout execution permission). On the other hand, when the usage rate of the system resource is less than the threshold, it is determined that the system resource is sufficient, the real logout execution is rejected (actual logout execution is rejected), and the pseudo logout is determined to be continued.

  The logout determination unit 24 acquires the system resource usage rate of the virtual PC server 10 from the virtual environment management server 30. The virtual environment management server 30 is an information processing apparatus that manages the virtual PC 110 and the virtual PC server 10. The virtual environment management server 30 periodically acquires information such as the system resource usage rate from the virtual PC server 10 and notifies the logout determination unit 24 of the information. doing. Here, a mechanism for acquiring information on the resources of the virtual PC 110 and the virtual PC server 10 in software installed in the virtual environment management server 30 and the OS of the virtual PC server 10 is prepared. For example, in vCenter Server of VMWare, there is a method that periodically acquires system resources such as the CPU and memory usage of the ESXi host and virtual machine to be managed, and refers to the information from an external machine . By using such a technique, the virtual environment management server 30 acquires information on the system resources of the virtual PC server 10.

[Operation]
Next, the operation of the information processing system described above will be described with reference to the flowcharts of FIGS. Here, it is assumed that the virtual PC server 10 provides the logged-in user terminal 40 by incorporating the user profile of the user into the virtual PC 110.

  Then, when the user terminal 40 logs out the virtual PC 110, the pseudo logout processing unit 112 in the virtual PC 110 detects the occurrence of the logout request, and performs the pseudo logout (step S1 in FIG. 3). That is, the virtual PC server 10 locks the operation from the user terminal 40 while keeping the user profile incorporated in the virtual PC 110.

  After that, the logout execution unit 23 determines whether it is possible to sequentially instruct the real OS logout to the guest OS 111 of each virtual PC 110 that has been pseudo-logged out at an arbitrary time set by the system administrator. The logout determination unit 24 is confirmed (see step S2 in FIG. 3 and arrow Y1 in FIG. 2). The time set by the system administrator is, for example, a time zone in which the usage rate of the virtual PC 110 is low, such as midnight, but is not limited to this time. In addition, determination and execution of actual logout are sequentially performed using arbitrary values such as the order of pseudo logout times and the order of IDs allocated to the virtual PC 110 and the user. As described above, the real logout is executed in a short time in a multiple manner without sequentially determining and executing the real logout for the plurality of virtual PCs 110 and sequentially performing the virtual logout 110 for each virtual PC 110. This is to reduce the system load due to.

  Then, the logout determination unit 24 confirms the information on the system resource usage status of the virtual PC server 10 that is periodically acquired from the virtual environment management server 30 and checks whether there is room in the system resources. (See steps S3 and S4 in FIG. 3 and arrow Y2 in FIG. 2). Specifically, the logout determination unit 24 compares the usage rate of the system resource with a threshold value.

  If the usage rate of the system resource is less than the threshold, the logout determination unit 24 determines that the system resource is sufficient (Yes in step S4 in FIG. 3), and notifies the logout execution unit 23 that the actual logout execution is rejected. A reply is made (step S7 in FIG. 3). When the logout execution unit 23 returns a real logout execution rejection from the logout determination unit 24, the logout execution unit 23 continues the pseudo logout without executing the real logout for the guest OS 111 of the target virtual PC 110 (step in FIG. 3). S8).

  On the other hand, when the usage rate of the system resource is equal to or greater than the threshold value, the logout determination unit 24 determines that the system resource has no room (No in step S4 in FIG. 3), and performs the actual logout execution permission. It returns to the unit 23 (step S5 in FIG. 3). When the logout execution unit 23 returns a real logout execution permission from the logout determination unit 24, the logout execution unit 23 instructs the guest OS 111 of the target virtual PC 110 to perform a real logout (see arrow Y3 in FIG. 2). Then, the guest OS 111 of the virtual PC instructed to perform real logout cancels the pseudo logout state of the virtual PC 110 that is performing pseudo logout. That is, the guest OS 112 of the virtual PC 110 performs user logout processing (actual logout) for releasing the user profile incorporated in the virtual PC 110 (step S6 in FIG. 3).

  As described above, in the present invention, first, when the system resources of the virtual PC server 10 have a margin, the virtual PC 110 continues the pseudo logout, and the number of times of copying the user profile which is an advantage of the pseudo logout is reduced. It is possible to reduce the load. On the other hand, when the system resources of the virtual PC server 10 are not sufficient, an increase in the load on the virtual PC server 10 can be suppressed by performing actual logout.

  In addition, the actual logout is performed in order, not in parallel on all virtual PCs in the system. Thereby, the actual logout is not performed in a multiplexed manner in a short time, and the load due to the actual logout can be distributed and reduced.

  Here, in the above description, whether or not the actual logout is performed is determined based on whether the usage rate of the CPU or the memory is equal to or higher than the threshold, but based on other data indicating the operating status of the virtual PC server 10 or the virtual PC 110 You may go. Further, the threshold value to be compared when determining whether to perform actual logout can be set as appropriate by the system administrator.

  In the above description, the connection broker 20 (control device, control unit) is described as being configured by an information processing device different from the virtual PC server 10, but the connection broker 20 is provided in the virtual PC server 1. May be. That is, functions such as the logout execution unit 23 and the logout determination unit 24 included in the connection broker 20 may be provided outside the virtual PC server 10 or may be provided inside the virtual PC server 10.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a diagram for explaining the configuration of the information processing system, and FIGS. 5 to 6 are diagrams for explaining the operation of the information processing system.

[Constitution]
In addition to the configuration of the first embodiment described above, the information processing system according to the present embodiment includes an automatic update management server 50 connected via a network as shown in FIG. In the present embodiment, as described below, the criteria for allowing the logout determination unit 24 to permit actual logout are different from those in the first embodiment.

  The automatic update management server 50 stores automatic update schedule information of the guest OS 111 of each virtual PC 110. Then, the logout determination unit 24 in the present embodiment periodically acquires automatic update schedule information from the automatic update management server 50. Further, the logout determination unit 24 rejects execution of actual logout when the guest OS 111 of the virtual PC 110 is not scheduled to be automatically updated, and permits execution of actual logout when the guest OS 111 of the virtual PC 110 is scheduled to be updated automatically. .

[Operation]
Next, the operation of the information processing system in the present embodiment will be described with reference to the flowcharts of FIGS. Here, it is assumed that the virtual PC server 10 provides the logged-in user terminal 40 by incorporating the user profile of the user into the virtual PC 110.

  When the user terminal 40 logs out the virtual PC 110, the pseudo logout processing unit 112 in the virtual PC 110 detects the occurrence of a logout request, and performs pseudo logout (step S1 in FIG. 6). That is, the virtual PC server 10 locks the operation from the user terminal 40 while keeping the user profile incorporated in the virtual PC 110.

  After that, the logout execution unit 23 logs out whether it is possible to instruct the guest OS of the virtual PC, which has been pseudo-logged out, to perform actual logout sequentially at any time set by the system administrator. Confirmation is made with the determination unit 24 (see step S2 in FIG. 6 and arrow Y11 in FIG. 5).

  Then, the logout determination unit 24 checks the automatic update schedule information of the guest OS 111 of each virtual PC 110 that is periodically acquired from the automatic update management server 50, and checks whether there is an automatic update (step S3 ′ in FIG. 6). S4 ′, see arrow Y12 in FIG. 5).

  Specifically, when the guest OS 111 of the target virtual PC 110 does not have an automatic update plan (No in step S4 ′ in FIG. 6), the logout determination unit 24 returns a real logout execution rejection to the logout execution unit 23 (see FIG. 6). 6 step S7). When the logout execution unit 23 returns a real logout execution rejection from the logout determination unit 24, the logout execution unit 23 continues the pseudo logout without executing the real logout for the guest OS 111 of the target virtual PC 110 (step in FIG. 6). S8).

  On the other hand, when the guest OS 111 of the target virtual PC 110 has an automatic update schedule (Yes in step S4 ′ in FIG. 6), the logout determination unit 24 returns a real logout execution permission to the logout execution unit 23 (FIG. 6). Step S5). When the logout execution unit 23 returns a real logout execution permission from the logout determination unit 24, the logout execution unit 23 instructs the guest OS 111 of the target virtual PC 110 to perform a real logout (see arrow Y13 in FIG. 5). Then, the guest OS 111 of the virtual PC instructed to perform real logout cancels the pseudo logout state of the virtual PC 110 that is performing pseudo logout. That is, the guest OS 112 of the virtual PC 110 performs user logout processing (actual logout) for releasing the user profile incorporated in the virtual PC 110 (step S6 in FIG. 6).

  As described above, in the present invention, first, when there is no plan to update the guest OS 111 of the virtual PC 110, the virtual PC 110 is continuously logged out, and the number of times the user profile is copied, which is an advantage of the pseudo logout, is reduced. Mitigation is possible. On the other hand, when the guest OS 111 of the virtual PC 110 is scheduled to be updated, an increase in the load on the virtual PC server 10 can be suppressed by performing actual logout. That is, for the virtual PC 110 for which the update of the guest OS 111 is scheduled, the actual logout is scheduled at the time of such update, and therefore, the increase in the load on the virtual PC server 10 is suppressed by performing the actual logout before that. be able to.

  In addition, the actual logout is performed in order, not in parallel on all virtual PCs in the system. Thereby, the actual logout is not performed in a multiplexed manner in a short time, and the load due to the actual logout can be distributed and reduced.

  Here, in the above, the execution of the actual logout is determined based on whether or not the guest OS 111 of the virtual PC 110 is scheduled to be updated, but is determined based on whether or not another application incorporated in the virtual PC 110 is scheduled to be updated instead of the guest OS 111. Also good. Furthermore, the execution of the actual logout may be determined according to the application installation status in the virtual PC 110 without being limited to whether or not the application is scheduled to be updated. For example, the execution of the actual logout may be determined according to a situation such as an application restart schedule.

<Embodiment 3>
Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 8 is a block diagram illustrating a configuration of the information processing system.

  The information processing system according to the present invention includes a server device 200 that constructs and provides a virtual computer 210 incorporating a user profile for a logged-in user terminal. The virtual computer 210 includes a pseudo logout execution unit 211 that sets a pseudo logout state by locking an operation from the user terminal in a state where the user profile incorporated in the virtual computer 210 is held.

  Furthermore, the information processing system includes a control unit 220 that performs actual logout for releasing the user profile incorporated in the virtual computer 210 in the pseudo logout state according to the operating status of the virtual computer 210 constructed in the server device 200. ing.

  With the above configuration, pseudo logout is continued or actual logout is performed depending on the operating status of the virtual computer. Thereby, it is possible to reduce the load by reducing the number of times the user profile is copied, which is an advantage of the pseudo logout, or to suppress an increase in the load on the server device 200 by executing the actual logout.
