Cloud-mode virtualization method

The invention relates to a cloud-mode virtualization method. The cloud-mode virtualization method comprises the steps: creating a plurality of virtual servers, which are independent of one another, in each physical server; creating a resource pool, abstracting hardware resources of all the physical servers into logical resources and saving the logical resources in the resource pool, wherein the logical resources are used for being allocated or shared to the virtual servers; amending semantics of x86 CPU instructions, and enabling the amended x86 CPU instructions to directly support privileged instructions of the virtual servers. The cloud-mode virtualization method provided by the invention has the advantages that the construction and expansion costs of an IT (Information Technology) system are reduced, and meanwhile, the performance of the IT system is improved.
