摘要:
A computer program product and computer implemented method are provided for migrating a virtual machine between servers. The virtual machine is initially operated on a first server, wherein the first server accesses the virtual machine image over a network at a memory location within fabric attached memory. The virtual machine is migrated from the first server to a second server by flushing data to the virtual machine image from cache memory associated with the virtual machine on the first server and providing the state and memory location of the virtual machine to the second server. The virtual machine may then operate on the second server, wherein the second server accesses the virtual machine image over the network at the same memory location within the fabric attached memory without copying the virtual machine image.
