Hi, and thanks for the tips!

Net-ns cleanup gave an error deleting that particular namespace,
and with --force it threw a few exceptions and also failed to remove
that namespace. It is good to know
about those commands for the future though.

emer-reset seemed to have no effect, which makes sense, given Eugene's
comment.

I wound up rebooting the node, which destroyed all the bad namespaces.



I have been trying to debug a
problem where machines were unable to talk on a public network to the
outside
world, (although they could if they were routing through from a private
network) and I have run into what I think are a couple of misconfigurations
 (ovs_use_veth not enabled, and use_namespaces not enabled either for
the dhcp
agent) which I've corrected. I should find out fairly soon if I'm able
to get
traffic out of a VM which only has an interface on the public network.

Regards,

Andrew
