is it qemu 2.4 on proxmox4 ?
or do you have backported it from proxmox git to proxmox 3 ?

recently, we have switched network card pxe roms to efi roms,
and I have add a fix to qemu-server to keep old pxe roms in case of migration

They are multiple commits, but first commit is:
https://git.proxmox.com/?p=qemu-server.git;a=commit;h=ba9e10002f92ba31d157ddc2cf2c38a0472d725b

Hi, 

i've upgrade some systems from qemu 2.2 to 2.4 and was trying to migrate 
those VMs. 

But those migrations fail with: 
kvm: Length mismatch: 0000:00:12.0/virtio-net-pci.rom: 0x10000 in != 
0x40000: Invalid argument 
kvm: error while loading state for instance 0x0 of device 'ram' 

Is this a known bug? 

Stefan
