No, this is another unexpected change due to the virtio refactoring in
QEMU. The right fix is in QEMU, by adding a get_fw_dev_path
implementation in hw/virtio/virtio-bus.c.
We fixed it already for migration paths, it should be easy to do the
same for this.
Please Cc qemu-sta...@nongnu.org when sending the QEMU patch.
Thanks,
Paolo
