For the iproute part, the version in the RDO grizzly repo has already netns support.<br></div><div><br></div><div style>However, for the Linux kernel portion, it need namespace file descriptor feature (/proc/[pid]/ns/net stuff) to make 'ip netns xxx' work.

</div>That is the right config items enabled, however, there are<br>
internal implementation details that are missing. So what<br>
is in 2.6.32-358.6.1.el6.x86_64 is not sufficient.<br>

<br>
</div>RHEL 6.4 has already shipped and does not support it.<br>
<br>
If you are interested in helping testing the feature, please let me<br>
know.<br>
<br>
I have packages here for iproute2:<br>
<br>
<a href="http://et.redhat.com/~chrisw/rhel6/6.4/bz869004/iproute/netns.1/" target="_blank">http://et.redhat.com/~chrisw/rhel6/6.4/bz869004/iproute/netns.1/</a><br>
<br>
And will try to push out test kernel asap.<br>
