openvz for Debian Squeeze

I am still at the OpenVZ booth at LinuxTag 2010 in Berlin. At least two people asked me about the status of OpenVZ kernel for the upcoming Debian Squeeze. Specifically, they said, there is no openvz kernel in "testing" repository (i.e. what will become Squeeze when it will be released). My guess is some more people interesting in that, so here's the public answer.

We are working pretty close with the Debian kernel team, you can see some traces of that on either debian-kernel AT lists.debian.org or debian AT openvz.org mailing lists. Specifically, we work together to bring good quality OpenVZ kernel to Squeeze, and this was one of the main reasons for us to port to 2.6.32.

But yesterday we tried to search for openvz linux-image on packages.debian.org and it gave us no results for testing. I then emailed Max Attems (who maintains our kernels in Debian) and this is his response:
it should be there now, the switch to libata did uphold testing
transition of linux-2.6 for quite some time, so testing had an
outdated linux-2.6 for quite some while

Indeed, the kernel is now there. So yes, Squeeze will have OpenVZ kernel, and I guess it can also be used by people who switched to Ubuntu 10.4.

Thanks for the update on this - been trying to use LXC, and after seeing first-hand how its nowhere near production ready, it's absolutely astounding that the Ubuntu folks are pushing it. Given its current state, LXC is being moved at least 12-18 months down my roadmap.

On the other hand, it looks like I'll be digging into Debian kernel compiles later tomorrow; OpenVZ kernel or bust!

LXC vs. OpenVZ
Could anybody (preferably OpenvZ devs because they should know it quite good, but others are welcomed too) write some quick post about current status of LXC? And differences in features (currently implemented and working) between LXC and OpenVZ? And other observations in this area?

I am a long time OpenVZ user testing new kernels and I wonder where LXC currently is compared to OpenVZ.

Also I wonder if LXC already allows for nested containers? Like CT5 in CT3 on HN.

Maybe some quick blog post in this subject would be helpful for some people like me?

Good news
Is good to know that OpenVz inclusion in Debian Squeeze keep on moving, despite of some little interruption like that you describe.
I'm using OpenVZ in Debian testing since may 17 snapshot and works smoothly, is very stable. Thanks for your great work,

mainline kernel?
Are there any news on getting OpenVZ into mainline Linux kernel?

Does the kernel on squeeze come with CPU limiting support?

This is great! We use Debain Squeeze for bioinformatics university research. Before I had to re-compile the kernel. It was OK, but now installing OpenVZ as package form the official Debian repository make things much better! Thank you Kir. -Alex

Still no cpu limiting
Is there any chance we will get working cpu limiting (CPUS, CPULIMIT) in the near future, either with a stock Debian squeeze kernel or an external kernel provided by openvz?
2.6.18-20-ovz-amd64 I still use with lenny is pretty outdated, and without the possibility to limit a customer to 1 CPU it is almost useless for me.
ext4 is also broken in Debian, using btrfs is no option either because quote does not work there.
Thanks for your answer and the good work you've done in the past.
