Patent US 8,464,259

In one or more embodiments of the invention, migration of a virtual machine includes identifying a hardware resource which is accessed directly by a device driver of the virtual machine and generating an emulation of the hardware resource to simulate the hardware resource as experiencing an error. The current state of the virtual machine can then be transmitted to the destination host computer, wherein the current state includes the emulation which simulates the hardware resource as experiencing an error. In at least one embodiment, generating the emulation includes defining the error as one that triggers a reset of the hardware resource after migration of the virtual machine from the source host computer to the destination host computer.
