Comment 13 for bug 1034161

When I exec this command:
# sudo ip netns exec 3f68d8dc-b761-4cb9-a3bf-7e8c4a227da9 ip addr list
seting the network namespace failed: Function not implemented

Is it a problem with iproute2?

# ip -V
ip utility, iproute2-ss120319

I have update the linux kernel from 2.6.32-279.5.1.el6.x86_64, Now is:
# uname -a
Linux openstack-f3 3.2.28 #1 SMP Wed Aug 29 23:56:50 CST 2012 x86_64 x86_64 x86_64 GNU/Linux

Thanks
