Re: [libvirt]: Not able to login to container when cgroup is enabled

Hi All, On F12 i was playing with libvirt support for container. I am seeing two issue over here: 1> Not able to create a container when start cgconfig services. 2> When i stop cgconfig, then able to create a container, but seeing few error messages to libvirtd daemon. 3> After creation of container through libvirt, i am not able to touch any file or directory. Attached: vm1.xml , through which i created container. I referred following link: http://libvirt.org/drvlxc.html http://openvz.org/pipermail/devel/2008-September/014314.html Detailed Bug Report: When i create a container without starting "cgconfig" service, i am able to create but getting some error message in libvirtd daemon: [root@mx3950 ~]# libvirtd 14:47:24.556: warning : qemudStartup:565 : Unable to create cgroup for driver: No such device or address 14:47:24.647: warning : lxcStartup:1462 : Unable to create cgroup for driver: No such device or address libvir: Linux Container error : failed to connect to client socket: No such file or directory libvir: Linux Container error : failed to connect to client socket: No such file or directory libvir: Linux Container error : failed to connect to client socket: No such file or directory But when i start cgconfig service, then i am not able to open console for my container. Below is the detailed steps which i executed.
