MIGRATING AND SAVE RESTORING A VIRTUAL 3D GRAPHICS DEVICE |
摘要 |
A virtual graphics processing unit within a virtual machine may be restored by causing a reset to the virtual graphics processing unit. The state of the virtual graphics processing unit may not be saved during a migration or save and restore operation, but a reset of the virtual graphics processing unit may cause all applications with processes in the virtual graphics processing unit to re-start and thereby recreate the state of the virtual graphics processing unit. A hypervisor may include a separate graphics processor unit process that may present a virtual graphics processing unit to a virtual machine and communicate with a physical graphics processing unit in hardware. When a virtual machine may be restored after a save or migration, the hypervisor may cause the virtual graphics processor unit to reset and its state to be recreated.
