Abstract
A virtual machine recovery method, where after receiving a virtual machine recovery command for recovering a to-be-recovered virtual machine, a virtual machine management device obtains configuration information of the to-be-recovered virtual machine from a cloud server. Then the virtual machine management device creates, according to the configuration information, a recovered virtual machine and a local storage. After downloading basic system data from the cloud server, the recovered virtual machine is started according to the basic system data. When receiving an input/output (IO) request for accessing a first data of the to-be-recovered virtual machine, the virtual machine management device downloads the first data from the cloud server to the local storage.
