Document Type and Number:
WIPO Patent Application WO/2017/124829
Kind Code:
A1
Abstract:
The disclosure discloses a method and device for restoring a virtual machine, wherein the method comprises: a control node detects a virtual machine satisfying an off-site restoration condition, searches in a correspondence relationship between the virtual machine, a compute node, and an operating state for a first operating state corresponding to the virtual machine satisfying the off-site restoration condition, determines that the first operating state is an empty state, and changes a compute node corresponding to the virtual machine satisfying the off-site restoration condition in the correspondence relationship to be a target compute node; and the control node searches in the correspondence relationship for a second operating state corresponding to the virtual machine satisfying the off-site restoration condition, determines that the second operating state is an empty state, changes the second operating state corresponding to the virtual machine satisfying the off-site restoration condition in the correspondence relationship to indicate that a virtual machine is being rebuilt, and sends to the target compute node a message that off-site restoration is performed. The invention realizes a virtual machine satisfying an off-site restoration condition.
