Comment 8 for bug 1130029

@Serge

Please note that the "-x /etc/utah/bridged-network-vm.xml" part works well in
the lab, but to reproduce the issue locally the defaults are good enough.

The command that I've used to reproduce the problem is:
sudo -u utah -i run_utah_tests.py \
    -p lp:ubuntu-test-cases/server/preseeds/lxc.preseed \
    -i /path/to/server/iso \
    lp:ubuntu-test-cases/server/runlists/lxc.run
