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.

Managing memory in devices that host virtual machines and have shared memory

A system and method include initiating a live migration of a virtual machine from a first host machine to a second host machine. The system and method include calculating, using a live migration tool, a data limit for an incremental data copy. The system and method also include determining, using the live migration tool, that a set of modified data stored in the memory of the first host machine equals or exceeds the data limit. The system and method further include pausing operation of the virtual machine responsive to the set of modified data stored in the memory of the first host machine equaling or exceeding the data limit.
