Abstract:
Performing a checkpoint includes determining a checkpoint boundary of the checkpoint for a virtual machine, wherein the virtual machine has a first virtual processor, determining a scheduled hypervisor interrupt for the first virtual processor, and adjusting, by operation of one or more computer processors, the scheduled hypervisor interrupt to before or substantially at the checkpoint boundary.
