Abstract
A method includes identifying two virtual machines (VMs) to be migrated from a source host. The method further includes determining that the two VMs correspond to identical memory pages in a memory deduplicaiton module. The method further includes recording, in hypervisor memory, an indication that the two VMs correspond to the two identical memory pages in the memory deduplication module. The method further includes sending, by a processing device of the hypvervisor, a single memory page of the two identical memory pages to a first destination host.
