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?
Yes, we do. We can fix that problem as a stable-0.12 update though.
Right now, migration with pc-0.11 is broken in other areas too.
Ok. When it is fine to defer this to stable-0.12 then I have no
objections to merge it for 0.12 (assuming the seabios folks ack+merge
the seabios changes).
Note, I also needed this to quiet things a bit.

Note that I'll be offline for x-mas and newyear starting tomorrow, so
I will not be able to work on that until January.
No problem.
It's really unclear to me the best way to handle live migration. The
rom_offset is not enough because unfortunately it's not stable after
invocations of qemu. I think we're going to have to actually save the
some contents with the PCIDevices.
With hotplug this will become a issue indeed.
Yup.
Lets see how this works out in practice ...
BTW, the following works:
sudo x86_64-softmmu/qemu-system-x86_64 -hda ~/images/linux.img -snapshot
-m 512 -net nic,model=rtl8139,macaddr=56:54:32:12:34:56 -net
nic,model=e1000,macaddr=56:54:32:12:34:57 -net
nic,model=virtio,macaddr=56:54:32:12:34:58 -boot menu=on -net tap
-kernel /boot/vmlinuz-2.6.27.38-170.2.113.fc10.x86_64 -initrd
/boot/initrd-2.6.27.38-170.2.113.fc10.x86_64.img -append "ro"
Using the F12 menu, I can select any of the three option roms and it
network boots or I can select 'Legacy Option ROM' and it will boot from
-kernel. That is exceedingly cool :-) We just need to give it a proper
PnP header and advertise it as a BEV device so that we can give it a
meaningful name.
