Abstract
High availability of a virtual machine is ensured even when all of the virtual machine's IO paths fail. In such a case, the virtual machine is migrated to a host that is sharing the same storage system as the current host in which the virtual machine is being executed and has at least one functioning IO path to the shared storage system. After execution control of the virtual machine is transferred to the new host, IO operations from the virtual machine are issued over the new IO path.
