Basically, I'd say try 0.12.4, it should have a > few fixes in this area over 0.12.3. I was testing with qemu-kvm 0.12.4 but I'm having the same problem. I re-read the announce about qemu-kvm 0.12.4 sent by Avi, but I didn't find in it some reference about fixes related to Virtio. If there's anything else I can try, please tell me.
