Where is the container root?

Do I need to copy all host files to this > guest?? At minimum, the guest should have /sbin/init under its own root. On the last link you gave, see "A private root filesystem with busybox" for a very-simplified example. If you want a full-blown installation, then yes, you need to have a working OS installation in the guest. This can be created with yum, or copying from existing system, or using templates. > If yes, then, how can I apply security updates to lxc guests?? The way you do on normal system: yum update. ON THE GUEST. FWIW, the upcoming Ubuntu 12.04 will have excellent lxc support for both host and guest, with lxc command line tools (lxc-create, lxc-start, lxc-console, etc). Other systems might require more effort to get a fully working container. And to be honest, I'm not sure how good Centos 6.2 would function as a host do to somewhat-old 2.6.32 kernel. I have a short howto on how to create Centos5 guest: http://wiki.1tux.org/wiki/Lxc/Installation/Guest/Centos/5 . Haven't had time to create one for Centos6 guest yet, but at least the above should give an idea of how to install a guest manually. You might also want to look at templates/lxc-fedora from the lattest userspace tools tarball (http://lxc.sourceforge.net/download/lxc/) -- Fajar ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Lxc-users mailing list Lxc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/lxc-users
