I just noticed that once I upgrade to libvirt-0.9.6-1 from the
virt-preview
repo on my Fedora 15 machine I can no longer boot guests that use virtio
disks. I only get "Boot failed: could not read the boot disk".
Removing the disk and re-adding it as IDE drive allows KVM to boot from
the
disk (although the full boot obviously fails due to the hda/vda naming
difference but that's expected).
After downgrading to libvirt-0.8.8-7 again the problem goes away and the
guest boot fine from virtio disks.
Somewhere around 0.9.4 libvirt switched to use a different method to
indicate from which device to boot.

I think this causes Seabios to skip using extboot.bin for booting and
to try to directly boot from a disk.
If your Seabios version is too old, it won't support booting from
virtio disks directly.
The libvirt package should probably be updated to require seabios-bin>= 0.6.2.
Yes, that probably needs to happen to libvirt.spec when built for F16
(and thus imported into F15 via virt-preview). I'll tackle that, since
I've been making a couple other spec file patches lately.
