I’m using for my own servers LXC for about a year now. I’m still fed up about bugs introduced by the beta version of LXC (0.8b) present in Debian Wheezy. As now LXC project has released a stable version, I’ve looked at the Debian backports, but didn’t have any chance to find a newer version on it :-(. However, a version 1.0.4 exist on Debian Jessie. I took the Debian sources and recompiled them on Wheezy (available here).

So if you want to update from 0.8b to the 1.0.4 version, it’s easy, but you need to take care about changes between both versions. For example, automatic boot feature, which involves to make some changes in your current configuration to work properly. lxc-shutdown command doesn’t exist anymore, lxc-stop replace it for a graceful shutdown and have an optional argument if you want to force all process’ containers to switch off. Another good news is: the default wheezy template works like a charm out of the box đŸ˜€

Note: before going ahead, it’s better if you can switch off your containers as they won’t be seen anymore by lxc-list after upgrading until reboot. May be there is a solution to avoid it, but didn’t had the time to search it.

To install it with the required dependencies:

Now, you need to change your LXC configuration if you want them to automatically start at boot. Edit config file of each containers and add this line (eg. /var/lib/lxc/container/config):

You now have to reboot to validate new configuration. That’s it.


 

If you want to know, how I’ve made the packages, here is the procedure:
1. First, temporary insert the Jessie sources in your sources.list and add wheezy backports:

2. Get the sources:

3. Remove previously added jessie sources and apt-get update once again.
4. Install dependencies:

5. Finally make new packages:

.deb packages are now available. I hope that help you. I would like to send it to Debian backport team, but never did it in the past and unfortunately don’t have much time to spend in it for the moment. So if someone familiar have the time to do it, it will be a pleasure.

 

Update 16/01/2015: I updated this docuementation for the latest Jessie version (1.0.6-6)

  1. Thank you, only one important thing, IHMO all dependencies installation should be done before “2”.
