Hi Nimal, I am not sure to understand what you are trying to achieve. You created a system container, but you want to launch it as an application container. Can you give your use case if possible, so I may be able to give more clues on how to set ip up. Thanks -- Daniel Hi Daniel, I want to run my application on fedora as a container and use the libraries (/lib, /usr/lib) from the host (so my application container size is small). I did lxc-create but lxc-execute failed (I had sent a mail earlier on this). Suggestion was to use lxc-start itself and run as system container. I changed the fstab file and could share the lib directory. Please let me know if there are better solution for my use case. I would like to try it too.

You can import directories from the host into a contianer using bind mounts. For example, I have this in some of my systems - this is the fstab file named in a container config file: none /vservers/vdsx10/dev/pts devpts defaults 0 0 none /vservers/vdsx10/procproc defaults 0 0 none /vservers/vdsx10/sys sysfs defaults 0 0 none /vservers/vdsx10/dev/shm tmpfs defaults 0 0 #/usr /vservers/vdsx10/usr/ nonedefaults,bind,ro 0 0 /usr/lib/asterisk /vservers/vdsx10/usr/lib/asterisk nonedefaults,bind,ro 0 0 /var/lib/asterisk/moh /vservers/vdsx10/var/lib/asterisk/moh nonedefaults,bind,ro 0 0 /var/lib/asterisk/sounds/vservers/vdsx10/var/lib/asterisk/sounds nonedefaults,bind,ro 0 0 The first 4 lines ought to be faimilar, but the bottom ones are ones I use which are common over all containers on that host. /usr is commented out here - can't remember why - I'd need to go back through my notes for this instance, but it's sunday night here Gordon -- ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
