Abstract
A system and method include initiating a live migration of a virtual machine from a first host machine to a second host machine. A shared host physical storage includes first swapped out memory data associated with the first virtual machine from a first memory of the first host machine, and metadata including location information of the first swapped out memory data, and an identity of the associated first virtual machine. The system and method include copying memory data associated with the first virtual machine stored in the first memory to the second host machine. The system and method also include accessing, by a second hypervisor at the second host machine, the metadata stored in the shared host physical storage to determine location of the first swapped out memory data associated with the first virtual machine.
