  The impacted job is, 
  https://jenkins.qa.ubuntu.com/view/Raring/view/Smoke%20Testing/job/raring-desktop-amd64-smoke-default/97/

  
  Syslog is attached. This appears to be am intermittent issue though, since the consecutive runs have passed and the manual installations also succeeded and did not see thins issue.

  Steps:
  1. Do a preseed installation of raring desktop using utah. The automation instructions are below
  2. Reboot the machine
  (Utah for automated installation, the how to is given in http://utah.readthedocs.org/en/latest/introduction.html#how-to-start-running-tests)
  The steps are
  1. use the attached .preseed file (attachment 15) and .run file (attachment 16) to execute the following command (please provide the absolute path to the files and the iso)
          sudo -u utah -i  run_utah_tests.py -i /path/to/iso/raring-desktop-amd64.iso -p lp:ubuntu-test-cases/desktop/preseeds/default.cfg lp:ubuntu-test-cases/desktop/runlists/default.run -x /etc/utah/bridged-network-vm.xml
  2. Reboot the VM after the installation
