Not sure if this is quite it, but check the /etc/sudoers.d/quantum-sudoers
shipped with Ubuntu 12.04.

/etc/sudoers.d/quantum_sudoers:quantum ALL = (root) NOPASSWD:
/usr/bin/quantum-rootwrap

In /etc/quantum/quantum.conf it needs a matching setting for the
root_helper, such as:

root_helper = sudo /usr/bin/quantum-rootwrap /etc/quantum/rootwrap.conf

The pathname needs to match in both places. Also check dhcp_agent.ini and
l3_agent.ini.

I couldn't find a related packaging bug but others following the docs have
run into this on ubuntu.
