In the patches I sent, the flags are discarded across migration (so
all of the emulated devices come back).  Our drivers get in very early
after the domain is resumed after migration and re-issue the magic
writes which unplug the devices.  Saving them wouldn't cause us any
problems, though, so if that's easier for you then feel free to add
it.
