Re: Possible support for openvz also in the next version of stable

Hi Ben and Pavel

Quoting Ben Hutchings <ben@decadent.org.uk>:
I thought we had declared both OpenVZ and VServer as deprecated in
squeeze, but I misremembered - in fact only VServer was deprecated.

That is good news if you ask me.

Therefore I think we need to make a decision regarding OpenVZ in wheezy,
fairly soon; then, if we do not reinstate it, we must announce that

If OpenVZ is to be included in wheezy, the OpenVZ project and some
Debian developer must be prepared to support it on a baseline of 3.2.y
until the end of 2015 (and also support 2.6.32.y until the end of 2013).

I understand. I had a discussion with Pavel on openvz yesterday and he told me that they are going to port the changes to 3.4.y version, but maybe I can convince them to support it on an earlier release.

If you cannot do this then it may be that you can serve Debian users
better by providing your own APT repository and kernel packages.  The
Debian kernel team can probably provide you some help with setting that

I agree on that. There are good rhel kernels that I understand can be ported to Debian using alien, but I guess that is nothing that would be accepted in Debian. I do not even know how well they work on Debian in the current state. I have to check that.

The current status of OpenVZ support for 2.6.32.y is that the git
repository (git://git.openvz.org/pub/linux-2.6.32-openvz) has not been
updated for 10 months.  The longterm updates and
included major cfq and scheduler changes that conflicted with OpenVZ;
these have had to be reverted for Debian's OpenVZ flavour.  All we have
had in that time is, I think, 5 bugfix patches.

As I understand from openvz they have been a bit too focused on the rhel kernels.

Pavel, can you comment on the possibility to provide this support. I'm willing to help but I guess I need some support from you as well.

Best regards,

// Ola

As a necessary (but not sufficient) condition, you and the OpenVZ
project would have to support OpenVZ in the *current* Debian stable
release.  The last release based on 2.6.32.y was made in March.  For
our OpenVZ kernel configurations we had to revert all the scheduler
fixes made in due to conflicts which we obviously do not
have the necessary knowledge to resolve.

It seems to me that the OpenVZ project does not support longterm
releases other than RHEL.  That's fine by me, just so long as no-one
pretends otherwise.

And all the above was previously discussed in
