The guest visible change automatically raises the question:
Do we need to do something for -M pc-0.11? Like loading the pci roms
via fw_cfg too so the guest doesn't see the new pci rom bar?
Oh, and while thinking about compatibility issues: What about
migration? I think we have to save rom_offset in case $pcidevice has a
rom bar, otherwise your roms are gone after migration. Which you
wouldn't notice until reboot though.
Is 0.11 -> 0.12 migration supposed to work? That could become quite
nasty too. But maybe that is impossible anyway due to the switch to
seabios?
cheers,
Gerd
