Re: [libvirt-users] LXC Memory Limits wont work



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
