[Lxc-users] cgroups permission problem

[John]

Guido, Serge
Thank you for your insight.  the parent, /cgroup/cpuset/lxc, has 
cpuset.cpus however it hasnt been initialized to any number.  my 
hypothesis is /cgroup/cpuset/lxc/GE/cpuset.cpus therefore cannot be set 
as its parent hasnt been initialized.

im uncertain if clone_children is present, however i would suspect it is 
or else the qemu_kvm package for centos would run into serious problems.
is there a means i can use to check the presence of this flag without 
fetching the source?
