Method for implementing organizational architecture mode of kernel-based virtual machine (KVM)

The invention mainly relates to a kernel-based virtual machine (KVM) architecture and an optimization technique thereof. Based on a KVM, the software structure thereof is optimized to fulfill the purposes of reducing the host resource occupied by the virtual machine and providing more efficient virtual machine running mode. In particular, a VPCS (virtual process control structure) created for each virtual machine process provides a good interface for implementing direct mapping between a physical resource and a logic resource. Meanwhile, because the hardware virtualization technique needs the support of a hardware technique, but a big part of servers owned by current large data centers and companies do not support the hardware virtualization technique, the optimization technique enables the virtualization technique to play a greater role in the calculation resource of the part. Therefore, the invention has good application prospect.
