Hi Marcos, ovs-vsctl should be added to the sudoers file with the NOPASSWD option as described on the launchpad Quantum answers site: https://answers.launchpad.net/quantum/+question/184536
This email list is for issues specific to OVS itself, but not the OpenStack Quantum plugin built using OVS. Questions that require an understanding on OpenStack should be posted to the launchpad site.
