Ok, so the problem is probably Avocado process utility not able to
call brctl. Maybe wrong PATH configuration. But anyway, Avocado should
use the full path for the command. I will send a fix for that.
Could you please try to edit
"/usr/lib/python2.7/site-packages/virttest/utils_net.py", line 996,
replacing "brctl show" by "/usr/sbin/brctl show" and check whether it
works?
