Open Stack

Hi all,

I am running a Openstack Juno on a bunch of docker containers. When my
neutron-network container reboots, neutron dhcp logs has a bunch of

015-05-28 17:49:14.629 475 TRACE neutron.agent.dhcp_agent Stderr:
'RTNETLINK answers: Invalid argument\n' 2015-05-28 17:49:14.629 475
TRACE neutron.agent.dhcp_agent

I noticed that this is due to the fact that the namespace behaves
weird when the container comes back up:

# ip netns exec qdhcp-474bd6da-e74f-436a-8408-e10fe5925220 ip a
setting the network namespace
"qdhcp-474bd6da-e74f-436a-8408-e10fe5925220" failed: Invalid argument
# ls -la /var/run/netns/
total 8
drwxr-xr-x 2 root root 4096 May 29 14:43 .
drwxr-xr-x 9 root root 4096 May 29 14:43 ..
---------- 1 root root    0 May 29 14:43
qdhcp-474bd6da-e74f-436a-8408-e10fe5925220

So, the namespace does exist, but the kernel does not seem to recognize it.
Did anyone else see this problem? How should I fix it?

Thanks
