Hi Laszlo,
I have read the bug report, and confirmed that my efibootmgr possesses
the same problem.
BootCurrent: 0004

However I did not stumble into the problem. I checked with my EFI
preboot environment to make sure that virtio-blk DXE driver were
really in use to manage my disk.

Do you have any suggestions on why it cannot be reproduce on my side ?
Finally provide my virt-install options for reference.
virt-install --connect qemu:///system --name vmos123efi
--virt-type=kvm --os-type=linux --os-variant=opensuse12 --disk
path=/dev/system/vmos123efi --network bridge=br0,model=virtio
--cdrom=/home/linux/Downloads/openSUSE-12.3-DVD-x86_64.iso --vcpus=4
--ram 1024 --boot loader=/home/linux/OVMF/OVMF-f1f4721.fd
Thanks,
Michael
