Title:
  With DVR enabled instances sometimes fail to get metadata

Status in neutron:
  Fix Released
Status in neutron kilo series:
  New

Bug description:
  Rally scenario which creates VMs with floating IPs at a high rate
  sometimes fails with SSHTimeout when trying to connect to the VM by
  floating IP. At the same time pings to the VM are fine.

  It appeared that VMs may sometimes fail to get public key from
  metadata. That happens because metadata proxy process was started
  after VM boot.

  Further analysis showed that l3 agent on compute node was not notified
  about new VM port at the time this port was created.
