I just upgraded my Icehouse (using `apt-get update`  ;`apt-get
dist-upgrade`) and both dhcp agent and metadata agent died.

2014-08-13 14:00:15.113 3419 TRACE neutron.agent.dhcp_agent Stderr: 'Cannot
open network namespace "qdhcp-f0076840-43f3-4b2e-aa15-d6b2422e3795": No
such file or directory\n'

Full log: http://paste.openstack.org/show/94504/

I'm using DHCP (for IPv4), and static IPv6, it was working like a charm
until now.

But the Namespace is here, look:

root at psuaf-1:~# ip netns exec qdhcp-f0076840-43f3-4b2e-aa15-d6b2422e3795 ip
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode
DEFAULT group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
22: tap216bf57d-e8: <BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UNKNOWN mode DEFAULT group default
    link/ether fa:16:3e:2d:67:53 brd ff:ff:ff:ff:ff:ff

What can I do?!

I did not touched the configuration files, I mean, the config files are
there, untouched.

This is a production cloud and it is impossible to create new instances
right now...   :-/

Tks in advance!
