[fedora-virt] Suddenly KVM/virt-manager is failing on qcow2 images

[Scott Dowdle]

Greetings,

Opps, I replied back to the original within 5 minutes of it appearing on the list but I guess my reply did NOT include the fedora-virt list and only went directly to the original poster.

Anyhoo... we already have a fix for it and it is listed below.

Yeah, I had the same problem and thanks goes to nirik for pointing me to the following info that fixed it for me:

https://admin.fedoraproject.org/updates/libvirt-0.8.2-1.fc13

Read the notes.  What I did was edit the config and turn switch probing back... and edit my VM's config and change the disk type from "raw" to "qcow2".
