Title:
  nova calls libvirt but failed:Operation not supported

Bug description:
  Hi all:

  I use github to install nova and quantum, but when I launch an
  instance, nova-compute fails:

  Is it because user nova call libvirt to create a port so it has not
  enough permission?

  note1:I set up sudoer:
  root@node1:~# cat /etc/sudoers.d/nova_sudoers 
  Defaults:nova !requiretty

  nova ALL = (root) NOPASSWD: /usr/local/bin/nova-rootwrap

  
  note2:I login as root, execute " ovs-vsctl add-port", and succeed.

  root@node1:~# ovs-vsctl add-port br-int  tap89ed2dc0-2e
