Abstract: The present invention relates to a hybrid memory system with live page migration for virtual machine, and the system comprises a physical machine installed with a virtual machine and being configured to: build a channel for a shared memory between the virtual machine and a hypervisor; make the hypervisor generate to-be-migrated cold/hot page information and writing write the to-be-migrated cold/hot page information into the shared memory; make the virtual machine read the to-be-migrated cold/hot page information from the shared memory; and make the virtual machine according to the read to-be-migrated cold/hot page information perform a page migration process across heterogeneous memories of the virtual machine without stopping the virtual machine.
