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
