Abstract: A method and system for monitoring a virtual machine cluster comprising sending, by physical machine, state parameter query instruction to a virtual machine in the virtual machine cluster at a first preset time interval; sending response information to the physical machine in response to receiving the query; the physical machine determining that the virtual machine is faulty, in response to the response information beyond a second preset time, judging whether the faulty machine satisfies a restart condition, and sending a restart instruction to a second machine on which the faulty machine runs, if the faulty machine satisfies the restart condition, by the virtual machine; and restarting, the second physical machine, the faulty virtual machine according to the restart instruction. The disclosure can be used to monitor virtual machines and recover a faulty virtual machine, thereby improving the availability of the virtual machine cluster and shortening service intervals.
