Abstract
A virtual machine migration system that includes an initiator host that provides a virtual machine and receives an instruction to migrate the virtual machine to the target host. The initiator host moves, while the virtual machine is operating on the initiator host, virtual machine data for the virtual machine from a local memory area in a local memory system to a memory fabric memory area in a memory fabric memory system. A first portion of the virtual machine data in the local memory area and a second portion of the virtual machine data in the memory fabric memory area are accessible to the virtual machine and the initiator host during the movement of the virtual machine data. The initiator host stops, in response to all the virtual machine data being moved to the memory fabric memory area, operation of the virtual machine on the initiator host.
