I know this series carries a good bit of risk but I'd like to bring it in 0.12.0. Because this has a guest visible change to the PCI devices, we cannot carry it in stable-0.12 post release and I think the functionality it brings it's very important.
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?
