Comment 3 for bug 1523709

Using the following method since I'm running into https://bugs.launchpad.net/fuel/+bug/1521520 when trying to create environments via dos.py.

export ISO_PATH=/home/fuel/arch/fuel-8.0-264-2015-12-07_01-42-00.iso
export NODES_COUNT=6
export ENV_NAME=as-8.0-264-13
export VENV_PATH=~/venv-nailgun-tests-2.9
./utils/jenkins/system_tests.sh -t test -w $(pwd) -V $VENV_PATH -j testing -o --group=setup -i $ISO_PATH -k -K

(venv-nailgun-tests-2.9)fuel@qa-01:~/fuel-qa$ virsh net-dumpxml as-8.0-264-13_admin
<network connections='1'>
  <name>as-8.0-264-13_admin</name>
  <uuid>ca836b4c-ffa3-4c8e-a18a-13a4efd0c05f</uuid>
  <forward mode='route'/>
  <bridge name='fuelbr390' stp='on' delay='0'/>
  <mac address='52:54:00:e4:60:cc'/>
  <ip address='10.122.30.1' prefix='24'>
  </ip>
</network>

In comparison, here's the same from a working environment created via 2.9.12.
