[libvirt-users] libvirt cgroup



1. I am using libvirt 0.8.3 on fedora14  .  Acoording to 
     
http://berrange.com/posts/2009/12/03/using-cgroups-with-libvirt-and-lxckvm-guests-in-fedora-12/
     inorder to have libvirt memory  cgroup under a  pre specified group 
one should add  
 CGROUP_DAEMON="memory:/virt" to /etc/sysconfig/libvirtd and restart 
cgconfig service  and the
   libvirtd service . That did not help . any idea ?

2. Also : specifying a limit to the memory subsystem 
(/dev/cgroup/memory/libvirt/qemu/memory.limit_in_bytes)
    by echoing a value , does not propagate to a VM generated later under 
qemu  which is actually generated with a huge default
    value for memory.limit_in_bytes .
    Suppose there was such a limit . Should it   decline a generation of a 
VM that requests a higher memory size in its 
    XML file or the limit prevents the VM from consuming more that the 
specified cgroup limit when consuming a higher value
 

thanks
