Hi Ricardo:

I have not deployed quantum, but looking at your error message:

*RuntimeError:**
**Command: ['sudo', 'ip', 'netns', 'exec',
'qdhcp-308fa2d9-d600-462e-b09a-be007cb8a6e8', 'quantum-ns-metadata-proxy',

**Exit code: 1**
**Stdout: ''**

**Waiting for data... (interrupt to abort)*

I would guess it has to do with the sudo configuration on your system.
Typically, when quantum is installed it uses a special program called
"quantum-rootwrap" for sudoing, e.g.:

sudo quantum-rootwrap ip netns exec ...


Typically, when you install OpenStack from packages, it will configure sudo
(/etc/sudoers or /etc/sudoers.d) to allow quantum-rootwrap to do
passwordless sudo for commands needed by OpenStack.

See the docstring here:
https://github.com/openstack/quantum/blob/stable/grizzly/bin/quantum-rootwrap

How did you install quantum?
