I've been wondering why grub can boot from a virtio device but can't see virtio devices. I wanted to have a generic disk which would have a bios partition with grub modules and this would include grub.cfg from a second disk. I could use this image to boot all my virtual linux machines without the need to have a partition on a logical volume. This way I have a separate virtio boot lv with partitions and it works fine. It just doesn't seem as nice and I'm curious if there is a way to get it to work, meaning if for example using efi or some other kind of bios for qemu or grub module would help it. thanks mk
