Abstract:
Aspects of the disclosure provide for mechanisms for virtual machine migration. A method of the disclosure includes: initiating migration of a virtual machine from an origin computer system to a destination computer system; determining, by a processing device, whether network reconfiguration has been completed for the migration of the virtual machine; stopping, by an origin hypervisor running on the origin computer system, the virtual machine on the origin computer system in response to determining that the network reconfiguration has been completed; and starting, by a destination hypervisor running on the destination computer system, the virtual machine on the destination computer system. In some embodiments, determining whether the network reconfiguration has been completed includes determining whether the designation hypervisor has received a threshold amount of data addressed to the virtual machine.
