Title:
  network namespace error

Status in “iproute” package in Ubuntu:
  New
Status in “lxc” package in Ubuntu:
  Confirmed

Bug description:
  Hello,
  I am using latest stables lxc build from http://ppa.launchpad.net/ubuntu-lxc/stable/ubuntu on a OpenStack controller to run containers. The OpenStack is also using network  namespaces . When I boot the server without auto start the containers everything looks fine with the OpenStack network namespaces. If I boot lxc container with lxc-start the container starts and its networking is functioning, but network namespaces created before that , by OpenStack installation for example , become unusable with he following error:

   root@osctrl3dc02:~# ip netns exec vips ip a
   seting the network namespace failed: Invalid argument

  Here is the strace:

   open("/var/run/netns/vips", O_RDONLY)   = 4
   syscall_308(0x4, 0x40000000, 0x7fffc4d54e83, 0x7fffc4d54bf0, 0x430af0,
   0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
   0, 0, 0) = -1 (errno 22)

   As far as I know sys call_308 should set the namespace , but it seems
  it fails on accessing the /var/run/netns/vips

  It is strange that the permissions are altered: 
  root@osctrl3dc02:~# ls -alh /var/run/netns/vips
   ---------- 1 root root 0 Apr 14 08:48 /var/run/netns/vips

   This file have the following permission before I start the container
   -r--r--r-- 1 root root 0 Apr 12 14:01 /var/run/netns/vips

   If I destroy the vips namespace and create it again , keeping the lxc
  containers running, everything is back to normal, both containers and
  Openstack networking are working.

  Best regards,
