Okay, is that something that can be changed via a prom (setenv) command? If
not, is that something that could/should be added to OpenBIOS, or would that violate the spirit of getting OpenBIOS as close to OBP?
The HostID and MAC address are part of the idprom on Sun Machines. That's a 32-byte static rom area on pre-sun4v machines, you can see it as a property with "prtconf -pv" from Solaris, or with .properties from "/" at the ok prompt.
It's not supposed to be changeable by the customer, it's supposed to be fixed at the factory so the serial number is meaningful.
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?
