Ok
somehow the processes bypasses the group/namespace
under libvirt the cgroups.procs file (
/sys/fs/cgroup/memory/machine/lxc-4296-deb4.libvirt-lxc/cgroup.procs )
shows only one process
with the lxc tools the cgroups.procs file (
/sys/fs/cgroup/memory/lxc/debian/cgroup.procs )
shows up to all 11 processes
