Ok, I tried here with a default install, I think I know what might be
happening (even though I didn't get useful info to debug the problem
first). The qemu-kvm shipped with Fedora 14 don't have support to boot
from virtio disks, something that qemu-kvm upstream has for quite some
time now. So the install goes on, but on boot qemu-kvm can't boot the
recently installed virtio disk.
So, as a workaround, I ask you to add image_boot = yes to your
tests_base.cfg. Around line 2419, you'll see:
variants:
- @ide:
drive_format=ide
- scsi:
drive_format=scsi
- virtio_blk:
drive_format=virtio
Please add image_boot = yes to the virtio_blk variant, so the block
looks like this:
variants:
- @ide:
drive_format=ide
- scsi:
drive_format=scsi
- virtio_blk:
drive_format=virtio
image_boot = yes
That will resolve the problem. This incompatibility between what Fedora
ships and qemu-kvm upstream has given us enough headache. I'll post a
fix to the configuration file later.
