摘要：【中文】本公开提出一种云主机恢复方法和装置，涉及云计算技术领域。在本公开中，生成云主机创建时的镜像，当云主机出现异常时，利用事先创建的镜像创建一个新主机，将出现异常的云主机的系统盘挂载到新主机上，然后，利用新主机恢复出现异常的云主机。该方法使得云主机的恢复过程变得简单，并且降低了云主机的恢复代价，缩短了云主机的恢复时间。 【EN】The disclosure provides a cloud host recovery method and device, and relates to the technical field of cloud computing. In the disclosure, a mirror image when a cloud host is created is generated, when the cloud host is abnormal, a new host is created by using the mirror image created in advance, a system disk of the abnormal cloud host is mounted on the new host, and then the abnormal cloud host is recovered by using the new host. The method simplifies the recovery process of the cloud host, reduces the recovery cost of the cloud host and shortens the recovery time of the cloud host.
