[Lxc-users] lxc on Fedora 15

[Ramez Hanna]

I have failed to start a container on f15 although it worked fine on 14
here is the log

mounts
[root at hovercraft boss]# mount |grep cgroup
tmpfs on /sys/fs/cgroup type tmpfs
(rw,nosuid,nodev,noexec,relatime,mode=755)
cgroup on /sys/fs/cgroup/systemd type cgroup

cgroup on /sys/fs/cgroup/blkio type cgroup
(rw,nosuid,nodev,noexec,relatime,blkio)

it looks like lxc is trying to create the container's cgroup under systemd
which seems to be the wrong location
any leads on how can i debug further
how does lxc find where cgroup is mounted?
