C) scheduling of a plurality of virtual machines is used in the dummy machine system
In the present embodiment, VMM instructs by VM Entry among the VMX and VM Exit and realizes the conversion of system's control from VMM to the virtual machine.In VMM inside, by taking of 300 pairs of computer resources of scheduling virtual machine device 210 each virtual machine of control, thus the parallel processing of each functional software in the realization virtual machine 300.
Scheduling virtual machine device 210 is to carry out taking of 301,302,303 pairs of hardware resources of each virtual machine by the VT instruction database in the virtual machine monitor (VMM) 200 220, distributes to realize the virtual machine hardware reasonable resources.
When virtual machine sends the instruction that hardware 100 is called, will cause VM Exit operation (reception of this operation is finished by VT instruction database module), at this moment, VT processor 110 controls will be returned to virtual machine monitor (VMM) 200;
Scheduling virtual machine device 210 passes to virtual machine monitor 200 with the hardware call instruction that VM Exit instruction is brought with parameter and virtual machine identification information in the virtual machine monitor (VMM) 200, and virtual machine monitor 200 is carried out the hardware call instructions and called that hardware is carried out real operation and the acquisition result returns;
After this, virtual machine controller 200 calls VM Entry instruction, and will return to virtual machine with VM Entry instruction by the execution return results that virtual machine monitor 200 obtains.
(3) dummy machine system communication
Because the virtual machine in the embodiments of the invention has been divided into bench-type virtual machine behind a desktop type virtual machine and two, therefore also exist communication with collaborative in each dummy machine system of the present invention, mechanism such as this memory shared by providing among the VMM, message maps, event communication are achieved.Most typical example is that three independent virtual machine are all carried out network service by the Objunctive network adaptor that VMM fictionalized in the IP mode, and this machine-processed specific implementation is the software module in VMM inside, distributes to the virtual machine of difference in functionality by the mode of data packet queue.
For example, the function of user by gateway type virtual machine can connect a plurality of equipment and shared resource, and the main carrier of these resources storage-type virtual machine virtual machine normally, this moment gateway type virtual machine with dummy machine system of storage-type virtual machine formation.Between the different virtual machine share and the internal virtual network that cooperation with service is provided in by VMM in dummy machine system of the present invention and the respective service that is provided respectively by virtual machine and VMM are achieved.These services comprise route service, device discovery and ability description service, resource sharing and cooperation with service.
Route service: because the function difference of three virtual machines, for the safety that realizes dummy machine system and external network is isolated, Microsoft Loopback Adapter is dispensed on different IP network sections usually, have only gateway type virtual machine can realize the external network communication with system, VMM is by the route service of built-in software route service to provide network between the variant virtual machine to connect then.
