Understood, but a virtual environment is a little bit different, since the only serial number is going to be some sort of UUID that is generated either at VM start time or is generated and then maintained in a config file.  MAC addresses can be customized for VMs, as well.  Clearly 80000000 isn't a valid hostid, so what should OpenBIOS and/or Qemu be doing, here?
