Example one
Fig. 1 is a schematic structural diagram of a virtualization service system according to an embodiment of the present invention, where the system includes: the service virtual machine 11 and the at least one application virtual machine 12 communicatively connected to the service virtual machine 11, and the service virtual machine 11 and the application virtual machine 12 in this embodiment are located in the same device, which may specifically be located on the same computer or the same server.
The virtualization service system of the present embodiment is a microkernel operating system, for example, an Intewell operating system with a C/S structure. The service virtual machine 11 is configured to obtain a control right of the shared resource, and set the shared resource as a service through the service management function module 13 for registration; the application virtual machine 12 is configured to send a resource query request to the service management function module, so that the service management function module queries from the registered shared resource according to the resource query request, and accesses a service corresponding to the query resource in the service virtual machine when determining that service permission information fed back by the service management function module according to a query result is received.
Specifically, the service virtual machine 11 in this embodiment includes an allocation resource obtaining module 111; the resource allocation module 111 is configured to acquire an allocation resource and a control right allocation instruction, set the allocation resource as a shared resource according to the control right allocation instruction, and determine a control right for the shared resource.
It should be noted that, the configuration mode of the service virtual machine in the Intewell operating system is different from that of the virtual machine with a common function, and during configuration, the Intewell operating system allocates the resource to be shared and the control authority allocation instruction to the service virtual machine, and the service virtual machine specifically acquires the allocated resource and the control authority allocation instruction through the allocated resource acquisition module, and the allocated resource acquisition module sets the allocated resource as a shared resource based on Intewell operating system software and determines the complete control authority of the service virtual machine on the shared resource.
Optionally, the resource allocation obtaining module is further configured to generate a registration instruction according to the shared resource, and send the registration instruction to the service management function module, where the registration instruction includes an identifier of the shared resource, an access port, and an access right; and the service management function module is used for registering the shared resource according to the registration instruction.
In one specific implementation, the allocating resources acquired by the allocating resource acquiring module include: the resource identified as ID1, the resource identified as ID2 and the resource identified as ID3 are allocated, on one hand, the allocated resource acquisition module sets the allocated resource as a shared resource based on Intewell operating system software and determines the full control right of the service virtual machine on the shared resource. In addition, the service virtual machine may further generate a registration instruction according to the determined shared resource through the allocated resource obtaining module 111, and transmit the generated registration instruction to the service management function module, so as to register the shared resource through the service management function module. The registration instruction specifically includes an identifier of the shared resource, an access port, and an access right, for example, the registration instruction includes a shared resource identifier-ID 1, an access port-001, and an access right-all application virtual machines in the system have a use right. The service management function module 112 determines the resource identified as ID1 from the allocated resources as a shared resource according to the registration instruction, and sets the access right of the shared resource to public, that is, other application virtual machines in the system have the right of use. Of course, the service management function module in this embodiment may also set the access right of the shared resource determined according to the registration instruction to be partially open, and the security of the shared resource may be ensured by setting the access right of the shared resource.
Optionally, the resource query request includes an identifier of the query resource; and the service management function module is used for sending service permission information to the application virtual machine when the query resource is determined to be the registered shared resource meeting the access right according to the identifier of the query resource, wherein the service permission information comprises the identifier of the shared resource and the access port.
Optionally, the service management function module is further configured to send service alarm information to the application virtual machine when it is determined that the query resource is a non-registered shared resource, or the query resource is a registered shared resource but does not satisfy the access right.
However, in actual application, the service management function module may be located inside the service virtual machine or outside the service virtual machine, and the service management function module is not limited in this embodiment. And the service management function module can provide registration service for the service virtual machine and can also provide query service for the application virtual machine. The specific process of the service management function module in providing the query service for the application virtual machine is as follows: when the application virtual machine needs to use the resources allocated to the service virtual machine in order to complete the specified task, the application virtual machine sends a resource query request to the service management function module, the service management function module judges whether the queried resources are available according to the identifiers of the queried resources contained in the resource query request, and if the queried resources are available, the application virtual machine sends service permission information containing shared resource identifiers and access ports to the application virtual machine, so that the application virtual machine accesses the services corresponding to the queried resources in the service virtual machine from the determined access ports to obtain shared resource services; and if the service management function module judges that the resources inquired by the application virtual machine are unavailable, directly sending service alarm information to the application virtual machine to prompt that the resources inquired by the application virtual machine do not exist or do not have access authority.
It should be noted that, the condition that the service management function module determines that the queried resource is available is as follows: the query resource is a registered shared resource, and the application virtual machine initiating the query has access rights to the registered shared resource. And the condition that the service management function module judges that the inquired resource is unavailable is as follows: inquiring whether the resource is a non-registered shared resource; or the query resource is the registered shared resource, but the application virtual machine initiating the query does not have the access right to the registered shared resource. In addition, the service management function module may also provide an uninstall service, a restart service, and the like, and in the present embodiment, the description is given only by taking a registration service and an inquiry service as examples, and the service type of the service management function module is not specifically limited.

The application virtual machine is used for accessing the hardware resource from an open device access port, a read device access port or a write device access port, namely an open/read/write interface of the Intewell system standard, to acquire the hardware resource service when determining that the service permission information for the hardware resource is received; or, when determining that the service permission information for the software resource is received, specifically, the software resource may be accessed from a standard Berkeley socket interface to obtain a software resource service; or, when it is determined that the service permission information for the data resource is received, the data resource may be accessed from an open file access port, a read file access port, or a write file access port, that is, a C library fopen/fread/fwrite interface, to obtain the data resource service. Of course, the access interface corresponding to each resource in the present embodiment is merely an example, and is not particularly limited thereto.
According to the technical scheme of the embodiment of the invention, the service virtual machine registers the acquired shared resource, so that the application virtual machine can use the registered shared resource on the service virtual machine according to the working requirement, and the normal realization of the service by the application virtual machine by using the shared resource and the working operation effect of the whole system are ensured.

It should be noted that, the application virtual machine and the service virtual machine in this embodiment may implement their corresponding functions based on Stub code, and the functional framework corresponding to each virtual machine has been constructed based on Stub code. In the specific running process, the user only needs to care about specific logic processing and does not need to care about specific contents of IPC programming, thereby facilitating the operation of the user. Of course, the application virtual machine and the service virtual machine may also implement their corresponding functions based on other types of codes, which is merely an example in this embodiment and is not limited to the specific types of codes implementing the functions.
Fig. 3 is a schematic view of a communication principle of the virtualization service system in this embodiment, and the service virtual machine may be communicatively connected to a plurality of application virtual machines through an inter-process communication module. When the application virtual machine obtains a resource query request input by a user, the resource query request is subjected to data packet encapsulation, a data serialization technology is adopted in the data packet encapsulation process, the encapsulated resource query request is sent to the service virtual machine through the IPC module according to a specified protocol, the service virtual machine unpacks the received protocol data, and a data deserialization technology is adopted in the protocol data unpacking process to obtain the identifier of the query resource contained in the resource query request. The IPC module is adopted to carry out communication connection on the service virtual machine and the application virtual machine by adopting a specified protocol, so that the accuracy of data transmission can be ensured, and the data serialization and deserialization technology is adopted to carry out encapsulation and decapsulation on data, so that the safety of the data in the transmission process can be ensured. According to the technical scheme of the embodiment of the invention, the service virtual machine registers the acquired shared resource, so that the application virtual machine can use the registered shared resource on the service virtual machine according to the working requirement, and the normal realization of the service by the application virtual machine by using the shared resource and the working operation effect of the whole system are ensured. The IPC communication module adopts a specified protocol to perform communication connection on the service virtual machine and the application virtual machine, so that the accuracy of data transmission can be ensured.
EXAMPLE III
Fig. 4 is a virtualization service method provided by an embodiment of the present invention, which may be executed by a virtualization service system in an embodiment of the present invention. As shown in fig. 4, the method specifically includes the following operations:
step S101, the control right of the shared resource is obtained through the service virtual machine, and the shared resource is set as the service for registration through the service management function module.
Optionally, the service virtual machine includes a resource allocation obtaining module; the control right of the shared resource is obtained through the service virtual machine, and the control right comprises the following steps: the distributed resources and the authority distribution instruction are obtained through the distributed resource obtaining module, the distributed resources are set as shared resources according to the authority distribution instruction, and the control right of the shared resources is obtained.
Specifically, the resource allocation acquired by the resource allocation acquisition module includes: the resource identified as ID1, the resource identified as ID2 and the resource identified as ID3 are allocated, on one hand, the allocated resource acquisition module sets the allocated resource as a shared resource based on Intewell operating system software and determines the full control right of the service virtual machine on the shared resource. In addition, the service virtual machine may further generate a registration instruction according to the determined shared resource through the allocated resource obtaining module 111, and transmit the generated registration instruction to the service management function module, so as to register the shared resource through the service management function module. The registration instruction specifically includes the identifier, access port, and access right of the shared resource, for example, the registration instruction includes the resource identifier-ID 1, access port-001, and access right-all application virtual machines in the system have the right of use. The service management function module 112 determines the resource identified as ID1 from the allocated resources as a shared resource according to the registration instruction, and sets the access right of the shared resource to public, that is, other application virtual machines in the system have the right of use. Of course, the service management function module in this embodiment may also set the determined access right of the shared resource to be partially open according to the registration instruction, and may ensure the security of the shared resource by setting the access right of the shared resource.
Step S102, a resource query request is sent to the service management function module through the application virtual machine, so that the service management function module queries from the registered shared resources according to the resource query request.
The resource query request is sent to a service management function module in the service virtual machine through the application virtual machine, and the resource query request comprises an identifier of query resources.
Specifically, the service management function module in this embodiment may provide a registration service for the service virtual machine, and may also provide an inquiry service for the application virtual machine. The specific process of the service management function module in providing the query service for the application virtual machine is as follows: when the application virtual machine needs to use the resources allocated to the service virtual machine in order to complete the specified task, the application virtual machine sends a resource query request to the service management function module, the service management function module judges whether the queried resources are available according to the identifiers of the queried resources contained in the resource query request, and if the queried resources are available, the application virtual machine sends service permission information containing shared resource identifiers and access ports to the application virtual machine so that the application virtual machine can access the services corresponding to the queried resources in the service virtual machine from the determined access ports to acquire shared resource services; and if the service management function module judges that the resources inquired by the application virtual machine are unavailable, directly sending service alarm information to the application virtual machine to prompt that the resources inquired by the application virtual machine do not exist or do not have access authority.
It should be noted that, in the present embodiment, the application virtual machine is specifically connected to the service virtual machine through inter-process communication IPC module, and the IPC module uses a protocol of an execution protocol to transmit data. The specific protocol includes TCP, UDP, or a content sharing protocol, and the specific type of the specific protocol is not limited in this embodiment.
For example, when the application virtual machine obtains a resource query request input by a user, the resource query request is subjected to data packet encapsulation, the encapsulated resource query request is sent to the service virtual machine through the IPC module according to a specified protocol, and the service virtual machine decapsulates received protocol data to obtain an identifier of a query resource included in the resource query request. The IPC module is adopted to carry out communication connection on the service virtual machine and the application virtual machine by adopting a specified protocol, so that the accuracy of data transmission can be ensured.
Step S103, the application virtual machine accesses the service corresponding to the query resources in the service virtual machine when determining that the service permission information fed back by the service management function module according to the query result is received.
Specifically, when determining that the query resource is a registered shared resource satisfying the access right according to the identifier of the query resource, the management function module in the service virtual machine sends service permission information to the application virtual machine, wherein the service permission information includes the identifier of the shared resource and the access port. After receiving the service permission information, the application virtual machine extracts an access port from the service permission information, and accesses the shared resource through the access port to acquire the resource service.
It should be noted that the service management function module is further configured to send service alarm information to the application virtual machine when it is determined that the query resource is a non-registered shared resource, or the query resource is a registered shared resource but does not satisfy the access right. And the application virtual machine determines that the inquired resource does not exist or does not have the access right to the inquired resource according to the service alarm information.
The shared resources comprise hardware resources, software resources and data resources; the hardware resources include: input/output IO equipment, a network card, universal serial bus USB equipment, peripheral component interconnect standard PCI equipment or a serial port; the software resources include: a network protocol stack, an image processing algorithm or an encryption and decryption authorization algorithm; the data resources include: a file system.
Optionally, when determining that the service permission information fed back by the service virtual machine according to the query result is received, accessing the query resource may include: when determining that the service permission information for the hardware resource is received, specifically, the hardware resource may be accessed from an open device access port, a read device access port, or a write device access port, that is, an open/read/write interface of the Intewell system standard, to obtain a hardware resource service; or, when determining that the service permission information for the software resource is received, specifically, the software resource may be accessed from a standard Berkeley socket interface to obtain a software resource service; or, when it is determined that the service permission information for the data resource is received, the data resource may be accessed from an open file access port, a read file access port, or a write file access port, that is, a C library fopen/fread/fwrite interface, to obtain the data resource service.
According to the technical scheme of the embodiment of the invention, the service virtual machine registers the acquired shared resource, so that the application virtual machine can use the registered shared resource on the service virtual machine according to the working requirement, and the normal realization of the service by the application virtual machine by using the shared resource and the working operation effect of the whole system are ensured.
