Looking for VServer alternative

It seems like VServer is not something for long run because it does not seem to want to be upstream and there is also no good future for having it as patch in Debian for long run. So I should look for alternatives and probably migrate to some other solution while upgrading my server to Squeeze (once it is released or really close to the release).

There are various options, starting with OpenVZ, through Linux Containers (LXC) up to full virtualization (probably KVM based). With OpenVZ the situation won't be much better, so it is not a real option. For various reasons I don't want to go to full virtualization, I simply thing containers are good enough and avoid too much overhead in some situations.

So the only remaining solution seems to be LXC. There even seem to be some people who managed to migrate from VServer, which is good and will be definitely helpful. Now it's time to play with lxc a bit before I will try to implement it for real.
