Getting instance for '5a76cd30-fb51-11e2-a901-5254008aabee'
Creating rootfs using 'ubuntu'
=======================
This had happened twice out of 4 installations and happens with both amd64 and i386. Please see below link for more details.
https://jenkins.qa.ubuntu.com/view/Saucy/view/Smoke%20Testing/job/saucy-server-amd64-smoke-lxc/96/artifact/utah-12380-saucy-server-amd64_lxc.run_2013-08-01_10-08-42.yaml/*view*/

The impacted smoke tests are:
https://jenkins.qa.ubuntu.com/view/Saucy/view/Smoke%20Testing/job/saucy-server-i386-smoke-lxc/91/
and
https://jenkins.qa.ubuntu.com/view/Saucy/view/Smoke%20Testing/job/saucy-server-amd64-smoke-lxc/96/

Steps to reproduce:
1. Install utah using
   sudo apt-add-repository -y ppa:utah/stable
   sudo apt-get update
   sudo apt-get install utah

2. Now run
sudo -u utah -i run_utah_tests.py -i /path/to/saucy-server-amd64.iso -p lp:ubuntu-test-cases/server/preseeds/lxc.preseed lp:ubuntu-test-cases/server/runlists/lxc.run -x /etc/utah/bridged-network-vm.xml
