Virtual machines that utilize pass-through devices are migrated from a source host computer to a destination host computer. During preparation for migration, the pass-through device is substituted with an emulation handler that simulates the pass-through device experiencing errors. Upon successful migration, an error reporting signal is triggered to cause the device driver in the virtual machine to initiate a reset of the pass-through device at the destination host computer, upon which the pass-through device is mapped to the migrated virtual machine.
