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. See http://libvirt.org/git/?p=libvirt.git;a=commit;h=c3068d4d2381146ed46051ad636a928edea5c602 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.
