I am trying to install the latest EMANE on Fedora 19 and run the user demonstration outside the VM. The checkconfig shows a valid installation, but every time run of the first demo, it actually outputs

   /Waiting for lxc containers: 0 of 4 are running./
   /Waiting for lxc containers: 0 of 4 are running./
   /Waiting for lxc containers: 0 of 4 are running./
   /Waiting for lxc containers: 0 of 4 are running./
   /Waiting for lxc containers: 0 of 4 are running./
   /Waiting for lxc containers: 0 of 4 are running./
   /Waiting for lxc containers: 0 of 4 are running./
   /Waiting for lxc containers: 0 of 4 are running./
   /Waiting for lxc containers: 0 of 4 are running./
   /Waiting for lxc containers: 0 of 4 are running./
   /Continuing with 0 of 4 running lxc containers./

And lxc-ls gives no results at all.
So I checked the log file under /tmp/lxc-node/1/1, it is like/
/

   / lxc-execute 1395779714.270 ERROR    lxc_cgroup - Invalid argument

   /

And the lxc-checkconfig shows everything enabled.
I have spent weeks on googling this for possible solutions, but did not have any clue.
Please help me, if anyone knows the solution.

Many thanks,
Xin
