[libvirt-users] Again with same Cgroup issue :)

Hello All, From the last couple of days i have been spamming this mailing list with request for configuring Cgroup with libvirtd on Centos systems. I still can not find a permanent solution to limit host RAM to particular value,tried creating a separate hierarchy "mykvm" and changed in sysconfig/libvirtd after that vm's memory cgroup reflects this.But it is not obeying "memory.limit_in_bytes" set in "mykvm" group,i als specified it in cgrules.conf and restarted it.If i change that in "/cgconfig/memory/mykvm/libvirt/qemu/memory.limit_in_bytes " its working.But that is dynamic as i am not able to find a way to mention that in "cgconfig.conf". How can i make sub hierarchies follow what is set in parent cgroup? eg: if change variables in "/cgconfig/memory/mykvm" then all instances coming under "/cgconfig/memory/mykvm/libvirt/qemu/" should follow that value..How is it possible.Can you please help
