Abstract
Disclosed herein are systems and method for live migration of a guest OS, the method comprising: interrupting execution of the guest OS in the hypervisor on a source computing device, transferring a state of the guest OS from the hypervisor on the source computing device to a hypervisor on a target computing device, and resuming execution of the guest OS in the hypervisor on the target computing device without waiting for completion of pending I/O requests on the source, wherein the pending I/O requests are generated by the guest OS in the hypervisor on the source and have not been completed before the interruption of execution of the guest OS, and wherein after resuming execution of the guest OS, the guest OS in the hypervisor on the target computing device is allowed to generate new I/O requests without waiting for completion of pending I/O requests on the source computing device.
