Abstract
The present invention discloses a method for implementing hot migration of a virtual machine. In this method, a source virtual machine migration management apparatus on a source physical machine determines non-temporary data memory pages of a virtual machine on the source physical machine, copies the non-temporary data memory pages from the source physical machine to a target physical machine, cyclically copies dirty pages, which are generated in the process of copying the non-temporary data memory pages, from the source physical machine to the target physical machine until a ratio of a quantity of dirty pages which are not yet copied to a quantity of the non-temporary data memory pages is less than a preset value; and performs migration of the virtual machine when the ratio is less than the preset value.
