[Lxc-users] cgroups permission problem

[John]

Guido,
Alas, this appears to be the problem.  /cgroups/cgroup.clone_children 
does not exist.

Thanks for the assistance, ill likely begin testing with a new kernel.  
A workaround for this problem in RHEL/Centos that sidesteps the kernel 
recompile issue is to permit containers to have access to all CPUs.  
this will result in oversubscription however.
