Hi Nasir,

Thanks for your reply.
I can run the following command from bash successfully:

sudo -u neutron bash -c 'sudo nova-rootwrap /etc/nova/rootwrap.conf ip
netns exec 221bd74f7522b3eb169eff5388bc5bf6feb1388c319b61102750cdf269f223e3
ip link set ns466bfc41-a9 address fa:16:3e:de:aa:9f'

Is this what you mean?

Regards,
Reza
