Sorry, I should've been more clear about the user running the python 
script in my previous post.   The script runs as the testu user and is 
in the testu group.  I repeated the experiment this morning just to be sure:

[testu at kvm ~]$ ls -l /var/run/libvirt
total 16
srwxrwx--- 1 root testu     0 Mar 12 07:45 libvirt-sock
srwxrwxrwx 1 root testu     0 Mar 12 07:45 libvirt-sock-ro
drwxr-xr-x 2 root root   4096 Mar  8 13:05 network
drwxr-xr-x 2 root root   4096 Mar 11 16:17 qemu

[testu at kvm ~]$ virsh -c qemu:///system list --all
  Id Name                 State
