Abstract

The invention discloses a migration processing method of a virtual machine, a storage medium and computing equipment. The method comprises the steps that when a virtual machine is migrated to target host equipment, a first cache space corresponding to a first graphic processing unit in source host equipment is initialized, and the first cache space is used for storing a task corresponding to the first graphic processing unit; after the first cache space is initialized, an unexecuted task backed up in advance is loaded into the first cache space; and the unexecuted task is sent to a second graphic processing unit of the target host equipment. The technical problem that the virtual machine cannot be migrated to the target host machine under the condition of not interrupting the service in the thermal migration process of the virtual machine is solved.

Description

technical field [0001] The present application relates to the technical field of computers, and in particular, to a virtual machine migration processing method, a storage medium, and a computing device. Background technique [0002] In related technologies, the virtual machine on the source host is migrated to the target host through hot migration technology and continues to run. During the hot migration process, the memory of the virtual machine is sent from the source host to the target host through iterative copying. On the target host, re-create the process of the simulated processor Qemu, and restore the state and data of the device simulated by Qemu. For applications inside the virtual machine, there is a 200ms CPU freeze without interrupting the application. [0003] In the image processor passthrough scenario, the current hot migration solution is that the status and data of the GPU device on the source host cannot be copied to the graphics processing GPU device on ...
