Hi Erik,
We discussed this before, the last time you tried this. I include my reply from then:
Hi Erik,
Did you do a full reinstall rather than an upgrade? The VM definition should have survived an upgrade.
The create-build-slave-vm script has never been tested on 14.04, and it looks like libvirt now only supports the more sophisticated "storage pool" method when using non-raw disk formats. The long-term solution would be to switch to using storage pools; there is a "local directory" pool type, and it is probably a small change, but I don't have a 14.04 machine to test on currently, nor the time. I think the easiest solution would be to use a raw disk image instead of a qcow2 image, which the error message suggests should still work. Since you don't need to back up this VM, there aren't so many advantages to qcow2 anyway. I think you should be able to do this by modifying the relevant part of the create-build-slave-vm script from
--disk path=$vmdir/root.qcow2,format=qcow2,bus=virtio,size=50
to
--disk path=$vmdir/root.img,bus=virtio,size=50
The only change should be that the image will now take 50 GB of real disk space, rather than only taking that space when it is actually used.
Can you try this change to the script?
