[Lxc-users] Archlinux 3.0 Kernel update breaks LXC

[lxc at jelmail.com]

Hello,

I a quite desparately in a stuck situation because my recent ArchLinux
update to the 3.0 kernel version has broken my LXC. I've reported this on
the Arch forum but am also asking here because I hope there's a better
concentration of Arch users on the LXC list than there are LXC users on the
Arch list.

I wouldn't normally cross-post but I am desperate as I have no system!!!

Basically, when I try to start a container I get this:

lxc-start -n mycontainer
lxc-start: No such file or directory - failed to rename cgroup
/cgroup/1781->/cgroup/mycontainer
lxc-start: failed to spawn 'mycontainer'
lxc-start: No such file or directory - failed to remove cgroup
'/cgroup/mycontainer'
[root at myhost ~]#

Here is my checkconfig and uname:

lxc-checkconfig
--- Namespaces ---
Namespaces: enabled
Utsname namespace: enabled
Ipc namespace: enabled
Pid namespace: enabled
User namespace: enabled
Network namespace: enabled
Multiple /dev/pts instances: enabled

--- Control groups ---
Cgroup: enabled
Cgroup namespace: missing
Cgroup device: enabled
Cgroup sched: enabled
Cgroup cpu account: enabled
Cgroup memory controller: enabled
Cgroup cpuset: enabled

--- Misc ---
Veth pair device: enabled
Macvlan: enabled
Vlan: enabled
File capabilities: missing

Note : Before booting a new kernel, you can check its configuration
usage : CONFIG=/path/to/config /usr/bin/lxc-checkconfig

[root at myhost ~]# uname -a
Linux myhost 3.0-ARCH #1 SMP PREEMPT Sat Aug 6 16:18:35 CEST 2011 x86_64
Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz GenuineIntel GNU/Linux

Please help, I am most desparately stuck as my desktop is in a container!!! 

Anyone else got this? Any suggestions for a solution? 

Thank you.
