So I can confirm that booting off VirtIO disk. That is raw+LiLO and as
far as finding boot sector and showing up LiLO. Then I'm getting kernel
panic due to unable to open root-fs etc. Also booting off PXE works.
However SCSI disk doesn't work without "hack" mentioned above.

All with qemu-kvm-0.15rc1 and libvirt-0.9.4 without any "hacks". I'm not
going to play with lower versions, but I'm confident it's going to be
the same +/-.
