why official jenkins doesn't suffer from this?

** Description changed:

  On 14.04 ubuntu with icehouse bug fix release (2014.1.1), nova
  interface-attach command is failing (used to work well in previous
  versions), while trying to attach an interface to a live VM.
  
  Here is the exception in the nova-compute.log file:
