Oh! My bad. Nice catch.

mkdir /dev/cgroup
or if your /dev is managed by udev, then you probably want to tell udev to
create that directory every start-up. see
http://linux-vserver.org/util-vserver:Cgroups for how to do it at least
under debian lenny (ie "mkdir /lib/udev/devices/cgroup").
I had earlier created /dev/cgroup but as it disappeared after reboot. Now I don't see that issue but after the udev suggestion in the above wiki (I use fedora 12 that uses udev).
I still can't get it to work :-(
[root@1-fedora ~]# vserver newdeb start
/usr/local/lib/util-vserver/vserver.functions: line 1506: /dev/cgroup/newdeb/tasks: No such file or directory
Failed to start vserver 'newdeb'
[root@1-fedora ~]# mount | grep cgroup
none on /cgroup type cgroup (rw)
vserver on /dev/cgroup type cgroup (rw)
I do see files under /dev/cgroup.
[root@guhan-fedora dev]# ls -l /usr/local/etc/vservers/.defaults/cgroup
total 0
[root@guhan-fedora dev]# ls -l /lib/udev/devices/cgroup
total 0
One interesting thing I found is : while /dev/cgroup/newdeb/tasks does not exist, I can see that /dev/cgroup/<pid>/tasks exists where pid "seems" to be the pid of "vserver newdeb start" command.
