Really? How does it pxeboot on virtio then (it definitely does pxeboot on virtio)? > Does Ubuntu 14.04 have efi-virtio.rom? Yes. After 2 layers of symlinks you get to. ubuntu@trustytest:~$ ls -la /usr/lib/ipxe/qemu/efi-virtio.rom -rw-r--r-- 1 root root 220672 Jan 6 2014 /usr/lib/ipxe/qemu/efi-virtio.rom > It would break "-M pc-1.0" started on older 14.04, but I think that's > acceptable.
