Abstract:
Embodiments of the invention relate to receiving, by a first processor comprising a processing device, an indication that a migration of a virtual machine from the first processor to a second processor is to occur. The first processor transmits user datagram protocol (UDP) packets intended for the virtual machine to the second processor based on the indication. A signal is transmitted to the virtual machine to enter an offline state, wherein the offline states comprises a transfer of at least one of a central processing unit (CPU) state and a memory state, and wherein the virtual machine is configured to halt a processing of the UDP packets in response to receiving the signal. The virtual machine is reactivated once the migration of the virtual machine from the first processor to the second processor is complete. The virtual machine is instructed to resume the processing of the UDP packets.
