Comment 10 for bug 1226310

I did some further verification and this affects Debian Wheezy as well. As per libvirt defaults, non-root users are connected to qemu:///session not qemu:///system

Here are the results from a fresh installation:

root@jeosd7:~# cat /etc/debian_version
7.5

root@jeosd7:~# virsh uri
qemu:///system

root@jeosd7:~# su -l gfidente
gfidente@jeosd7:~$ virsh uri
qemu:///session
