Abstract
A migration method and a migration system of a virtual machine are disclosed. The method includes: a virtual machine detecting whether a migration instruction is received, wherein the virtual machine runs on a first processor of a first host machine; the virtual machine calling and obtaining video memory data generated in the first processor if the migration instruction is detected; and the virtual machine migrating the video memory data to a second processor of a second host machine. The present disclosure solves the technical problem that a virtual machine using a GPU pass-through mode fails to perform a live migration between host machines in the existing technologies.
