I'm successfully using lxc via lbivirt. I doubt ns subsystem of cgroups because I usually disable it that is the difference between my configuration and yours and if I enable it I also get the same error. So could you try without ns? like: mount -t cgroup -o memory,devices,cpu,cpuacct none /cgroup I think libvirt lxc still contains a problem around ns subsystem. ozaki-r > > libvirt 0.7.4+ > kernel 2.6.32 (am i missing a CONFIG_*?) > > thanks for your time > > -- > Libvir-list mailing list > Libvir-list@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/libvir-list > -- Libvir-list mailing list Libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
