Hi, it seems that during vserver start /usr/sbin/vspace creates a cgroup that conflicts with the cgroup to be used when creating /etc/vserver/name/cgroup Please see below: # ls -la /dev/cgroup total 0 drwxr-xr-x 3 root root 0 Jan 22 13:02 . drwxr-xr-x 12 root root 14700 Jan 22 09:29 .. -rw-r--r-- 1 root root 0 Jan 22 09:31 cpuacct.usage -rw-r--r-- 1 root root 0 Jan 22 09:31 devices.allow -rw-r--r-- 1 root root 0 Jan 22 09:31 devices.deny -rw-r--r-- 1 root root 0 Jan 22 09:31 devices.list -rw-r--r-- 1 root root 0 Jan 22 11:24 notify_on_release -rw-r--r-- 1 root root 0 Jan 22 11:52 release_agent -rw-r--r-- 1 root root 0 Jan 22 11:53 tasks # mkdir /etc/vserver/deb4/cgroup # vserver deb4 start /usr/lib/util-vserver/vserver.functions: line 1491: /dev/cgroup/deb4/tasks: No such file or directory Failed to start vserver 'deb4' # ls -la /dev/cgroup total 0 drwxr-xr-x 3 root root 0 Jan 22 13:02 . drwxr-xr-x 12 root root 14700 Jan 22 09:29 .. drwxr-xr-x 3 root root 0 Jan 22 13:02 26191 -rw-r--r-- 1 root root 0 Jan 22 09:31 cpuacct.usage -rw-r--r-- 1 root root 0 Jan 22 09:31 devices.allow -rw-r--r-- 1 root root 0 Jan 22 09:31 devices.deny -rw-r--r-- 1 root root 0 Jan 22 09:31 devices.list -rw-r--r-- 1 root root 0 Jan 22 11:24 notify_on_release -rw-r--r-- 1 root root 0 Jan 22 11:52 release_agent -rw-r--r-- 1 root root 0 Jan 22 11:53 tasks That cgroup (in this case 26191) is created while running "exec $_VNAMESPACE --new" during the exceution of /usr/sbin/vserver. # /usr/sbin/vspace --version vspace 0.30.216-pre2772 -- manages spaces This program is part of util-vserver 0.30.216-pre2772 Is there a way to create the right cgroup (deb4) from the beginning ?
