As processor technology develops, a plurality of core processors are implemented in a single physical processor. In addition, a virtualization technology capable of efficiently operating a plurality of core processors is being used.

For example, a virtualization layer may be formed on a host OS (or a kernel) that manages hardware resources (e.g., a plurality of core processors), and a virtualization layer may be formed by hardware resources Processor), thereby realizing virtualization. Alternatively, virtualization can be realized by operating a virtual machine monitor (VMM) or a hypervisor between a hardware resource (e.g., a plurality of core processors) and a host operating system (or kernel).

In a datacenter environment, multiple virtual machines (VMs) can be running on one physical machine. Management such as creating, deleting, starting, and restarting a virtual machine can typically be performed by a virtual machine manager, which may be implemented as a standalone application or as part of an operating system.

Isolation is provided between multiple virtual machines. Isolation provides high reliability by preventing these problems from affecting other virtual machines, even if one of the virtual machines experiences a problem.

The first virtual machine monitor 422 provides the context to the processor processing unit 425-2 and the context that can not be processed by the processor processing unit 425-2 (e.g., a global exception context, etc.) Processor 426-1.

The first virtual machine monitor 422 may monitor the context processed by the first virtual processor 426-1 and provide the virtual machine state management unit 428 for managing the state of the virtual machine.

FIG. 7A is a flowchart illustrating an operation of a first virtualization apparatus included in a remote processing apparatus of a virtual machine processor according to another embodiment of the present invention. FIG. FIG. 2 is a diagram illustrating an operation process of a second virtualization apparatus provided in a processing apparatus. FIG.

Referring to FIG. 7A, the state processing unit 425-1 processes the initialization of the first virtual processor 426-1 (S311).

For example, the first virtual processor 426-1 and the second virtual processor 426-2 execute in the two communicable nodes, that is, the status processor 425-1 and the processor processor 425-2, do.

For initialization of the first virtual processor 426-1, the state of the virtual machine is defined by the virtual machine state manager 428 and accordingly, one virtual processor context is created.

The first virtual processor 426-1 creates a connection with the second virtual processor 426-2 and after confirming that it waits for the request of the connected second virtual processor 426-2, (S312).

Thereafter, the first virtual processor 426-1 waits for the result of the second virtual processor 426-2 (S313). Upon receiving the execution result of the second virtual processor 426-2, the first virtual processor 426-1 first confirms and processes the global exception process according to the result, and then proceeds to step S312, 2 processing request of the virtual processor 426-2 (S314).

If there is no processing for the global exception in step S314, the first virtual processor 426-1 waits for an input / output event (S315). If the input / output event is generated, the first virtual processor 426-1 proceeds to step S312, And transfers the context to the second virtual processor 426-2.

When the operation of the virtual processor is completed, the first virtual processor 426-1 may transmit the control context indicating the termination of the virtual processor to the second virtual processor 426-2 (S316).

Referring to FIG. 3B, the processor processor 425-2 processes the initialization of the second virtual processor 426-2 (S321). Then, the second virtual processor 426-2 waits for a context processing request from the first virtual processor 426-1 (S322).

When the second virtual processor 426-2 receives the context processing request from the first virtual processor 426-1, the second virtual processor 426-2 performs the processing of the corresponding context (S323). At this time, the second virtual processor 426-2 can check whether the requested context is a processable process (S324).

If the requested context is a processable context (S324-Yes), the second virtual processor 426-2 proceeds to step S325, and if the requested context is a non-processable context (S324-No), the process proceeds to step S330 do.

Next, the second virtual processor 426-2 stores the host status of the processor processor 425-2 (S325), loads the requested virtual processor context (S326), and loads the loaded virtual processor context (S327).

If an exception occurs in the context during the execution of the virtual processor context (S328-Yes), the second virtual processor 426-2 uses the host state of the processor processor 425-2 stored in step S325 to recover (S329). The second virtual processor 426-2 checks whether the generated exception is a locally processable exception (S330). If the exception is a locally processable exception (S330- Yes), the second virtual processor 426-2 classifies the exception as a region exception process And performs an area exception process (S331). On the other hand, if the previously generated exception can not be handled as a region exception in the second virtual processor 426-2, the second virtual processor 426-2 proceeds to step S332 and determines that the corresponding context can not be executed To the state processing unit 425-1.

In a conventional virtual machine system, a virtual processor has to be physically performed only in a processor provided in a single node. On the other hand, according to the remote processing apparatus and method of the virtual machine processor proposed in the present invention, the context of the virtual processor can be separated and executed in another remote physical node. In this way, by separating and processing the contexts to be processed by the virtual processors in different physical nodes, internal fragmentation of the processor resources that can occur in the cloud service provider can be realized.

Furthermore, it is possible to implement more virtual processors than the processors that can be accommodated at the physical node, and thus a virtual machine having a plurality of virtual processors can be provided.

In addition, the separated context can control the access control through the external / internal access window classification for the access method to the virtual processor descriptor, thereby minimizing the performance degradation of the virtual machine.
