Since a couple of months I successfully use LXC (Linux containers) on test and production machines on Ubuntu 12.04 LTS and on Debian Wheezy.
Although I am very confident in the abilities and performance of LXC, there was one little issue: LXC is marked as still in development on the official website (http://lxc.sourceforge.net):
The lxc is still in development, so the command syntax and the API can change. The version 1.0.0 will be the frozen version.
This could potentially be an issue for (security) audits or to get the acceptance of your superior.
A few hours ago, the (possible) roadmap for the stable version 1.0 has been announced on the lxc-devel mailing list:
This is the first alpha release for LXC 1.0. Current release schedule is:
- October: alpha2
- November: alpha3
- December: rc1
- January: rc2
- February: 1.0 final
