Hi all:
I use github to install nova and quantum, but when I launch an

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.
