Default openvz kernel wih lucid?

Hi,

i use openvz with ubuntu 8.04 (LTS) on my server.
All the newer releases have no openvz kernel.
Will be openvz available with ubuntu 10.04 (lucid)?

The problem is, that i can not use ubuntu karmic in the container (see
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/484240 ) so i have
to update the host system but there is no openvz kernel available.

Cheers,

Tom

Very unlikely. We are, however, working on getting really good LXC (the
container technology in the upstream linux kernel) support in Lucid.
I've never used OpenVZ myself, so I don't know what the upgrade path may
be like. :-/

LXC will be by default in Lucid. Here's a nice page from one of my
colleagues that explains how to do it:
http://stgraber.org/category/lxc

We have the same problem here, even with LXC. There's a problem with
init in Karmic. If you chroot in /var/lib/vz/<context> and do an apt
dist-upgrade on the current Lucid packages, it should work, at least for
testing purposes.

If you need stable containers, use a Hardy guest.

What means "really good LXC ... support" ?
- will LXC be in main or universe?
- What about Documentation? I can not find any wikipage on
wiki.ubuntu.com or help.ubuntu.com
- what about templates? is it easy to create a new container?
- is it possible to use other distros as containers?
- is it actually possible to tryout LXC with karmic? or do i need lucid
as hostsystem?

LXC is in the kernel, so it's naturally in main. Libvirt will very
likely be the primary way to manage LXC containers, and libvirt is also
in main.

I personally haven't worked on documentation at all yet, and I probably
wont for a while. We need all the help we can get writing documentation.

VMBuilder will be able to create containers.

Depends on the the other distro, really.

There are (were?) a few bugs in libvirt making this rather difficult,
but they are being fixed (have been fixed?), so
