Repairing virtual machine in cloud environment

A method for repairing a virtual machine in a cloud environment, the method comprising:

• downloading, by processing circuitry of a host machine that hosts a target virtual machine, a Live CD image corresponding to a target image identifier from an image repository to store in a target cloud block storage;
• mounting the target cloud block storage to the target virtual machine;
• and booting, via the target cloud block storage, the target virtual machine that has a system failure, wherein the target cloud block storage is created by a server device to store the Live CD image and to be mounted to the host machine;
• the target image identifier is obtained by the server device by querying an image database according to a virtual machine identifier of the target virtual machine;
• and the virtual machine identifier of the target virtual machine is included in a first request that is transmitted by a console to the server device to request to a repair of the target virtual machine.

A server device, comprising processing circuitry configured to:

• receive a first request that is transmitted by a console, the first request comprising a virtual machine identifier of a target virtual machine and requesting a repair of the target virtual machine;
• query an image database for a target image identifier of a pre-made live compact disc (Live CD) image corresponding to the virtual machine identifier;
• create a target cloud block storage for storing the Live CD image;
• and mount the target cloud block storage to a host machine that hosts the target virtual machine to cause the host machine to:
• download the Live CD image corresponding to the target image identifier from an image repository to store to the target cloud block storage, mount the target cloud block storage to the target virtual machine, and boot the target virtual machine via the target cloud block storage.
