I got confused, sorry. Let's try to enumerate what works and what does not.
Could you tell us which of the following combinations you tried
and with what result (works/doesn't)?
- virtio + raw + 0.12
- virtio + qcow2 + 0.12
- ide + qcow2 + 0.12
- virtio + raw + 0.13
- virtio + qcow2 + 0.13
- ide + qcow2 + 0.13
Thanks!
