Abstract
A hypervisor of a source host receives a request to migrate a group of virtual machines from the source host to a destination host. The hypervisor of the source host determines that a first virtual machine being migrated to the destination host shares a memory space on the source host with a second virtual machine on the source host. Upon receiving a request from the second virtual machine on the source host to access a first memory page of the shared memory space on the source host that has been migrated to the destination host, the hypervisor of the source host initiates migration of the second virtual machine to the destination host.
