Title:
  nova sometimes doesn't clean up neutron ports when VM spawning fails

Status in OpenStack Compute (nova):
  New
Status in nova-cloud-controller package in Juju Charms Collection:
  Invalid

Bug description:
  Hi,

  It appears that sometimes, nova doesn't clean up ports when spawning
  the instance fails. I'm using SR-IOV so I'm creating ports manually.

  Example :
  Create port with :
  $ neutron port-create <net_id> --name direct --binding:vnic_type direct

  Boot instance using said port :
  $ nova boot --image <image> --flavor <flavor> --key-name admin_key --nic port-id=<port-id from above> vm_direct

  If VM creation fails and the failed VM gets deleted, the port is still bound :
  $ neutron port-show direct2

  $ nova show 2aecc61b-e3c9-4b1f-9e47-574733705a91
  ERROR: No server with a name or ID of '2aecc61b-e3c9-4b1f-9e47-574733705a91' exists.

  This is similar to LP#1423845, but I do have the fix from that bug
  already in my code.

  Package versions are : 2:12.0.2-0ubuntu1~cloud0, running on trusty

  Thanks
