Migration of a guest from one server to another
Abstract:
Systems, methods and media for migration of a guest from one server to another are disclosed. In one embodiment, a first server, while hosting the guest, receives a signal from the second server that the migration is to occur. The first server presents the memory used by the guest as a virtual disk. The second server accesses this disk and copies its contents to the second server over the storage area network. The first server suspends operation of the guest, and after the memory of the guest is copied to the second server, the second server resumes operation of the guest.
