Hello, I'm testing lxc under Debian Wheezy with kernel linux-image-3.0.0-rc4-amd64(experimental repo) lxc-version 0.7.3 lxc-checkconfig reports "Cgroup namespace: missing" lxc-start -n db1 -f /var/lib/lxc/db1/config lxc-start failed to spawn 'db1' lxc-start No such file or directory - failed to remove cgroup '/cgroup/db1' Lxc works fine with 2.6.39-2-amd64 kernel. What did I miss ? Regards
