Title:
  interface-attach to external network a) works and b) results in
  undeletable instances

Status in OpenStack Compute (Nova):
  In Progress
Status in OpenStack Security Advisories:
  Invalid
Status in “neutron” package in Ubuntu:
  New
Status in “nova” package in Ubuntu:
  New

Bug description:
  2013.2.1 release of OpenStack, Neutron OVS plugin.

  Users where able to add interfaces using the 'nova interface-attach'
  command to the external network definition within the OpenStack
  deployment.  This appears to work and the ports are listed in nova
  port-list <uuid>.  However when deleting these instances, nova-compute
  throws the following error; its also not possible to delete the
  offending ports from the user tenant; this has to be done from an
  admin tenant:

  neutron port-delete <port>
  nova delete <uuid>
