Xen devel - Jul 2011 - Announcing Project Kronos: XenAPI on Debian and Ubuntu

Hi Xen users,

The XCP team would like to formally announce Project Kronos, our port of
XCP''s XenAPI toolstack to Debian and Ubuntu dom0. This will give users
the ability to install Debian or Ubuntu, and then just do ''apt-get
xapi''
in order to build a system that is (roughly) functionally equivalent to
a standard XCP distribution.

This project provides a number of benefits. First of all, it will
provide Xen users with the option of using the same API and toolstack
that XCP and XenServer provide. It will give early adopters the chance
to try out new changes to the XenAPI before they get released in new XCP
and XenServer versions. And because we''ve ported all of our toolstack
to
build on Debian, it''s now much, much easier to build our tools outside
of an SDK VM.

Our general roadmap for this project (and XCP in general) can be found here:

http://wiki.xen.org/xenwiki/XCP_Roadmap

Instructions for install the XenAPI toolstack on Debian can be found here:

http://wiki.xen.org/xenwiki/XAPI_on_debian

A list of project milestones, deliverables for each milestone, and
individual work items for the project can be found on this Google Docs
spreadsheet:

http://goo.gl/jX3Kc

For building the toolstack from source, Jon Ludlam has an autobuilder
repository on github here:

https://github.com/jonludlam/xapi-autobuilder

To use it, just clone the repository and type make. This will pull in
all the dependency repositories and build them using pbuilder. If you
want to build individual packages, dig into the build scripts a bit to
see what''s going on -- hopefully we''ll have a little better
documentation soon.

Please follow the instructions and play along! This is very much a work
in progress, and things are expected to change rapidly. We don''t expect
everything to work properly yet, but we think it''s ready enough to at
least share our progress. If you do decide to test this out, please
report any bugs you find or problems you encounter to the xen-api
mailing list, with the subject line "Xapi on Debian: <blah>".
There are
also XCP contributors lurking on #xen-api on freenode who may be able to
answer questions about build or install problems.

Thanks to everyone who''s helped out with this project, and to everyone
who is about to give it a try. Happy hacking!

Mike

Awesome! I am so excited to try this out! This will save me a fortune in
KVM-over-IP costs since I''m not fortunate to have my own data centre :)

Please keep up the good work - this is a great step in the right direction.

p.s. Will these xapi packages work with Xen 4+, Remus etc ?

They''re dependent on xen-4.1.1 at the moment, and for dom0 they require
linux-3.0.0. There are currently no plans for remus support, but that
doesn''t mean we''re not interested in it :-)

These packages are being built against Xen 4.1.1, and we plan on
tracking Xen unstable as closely as possible. There are no plans for
Remus integration, but we''re open to contributions ;) There is,
however,
a plan on integrating DRDB in a way that will allow us to do cross-pool
migration (http://wiki.xen.org/xenwiki/CrossPoolMigrationV2), and there
are two people who are working on OCFS2 and GlusterFS backends.

That''s correct, but there is no way to control it using xapi''s
XenAPI.
We also don''t have any plans to extend the API to provide Remus support
(though, as always, we welcome contributions). I would be interested to
hear what happens if you attempt to use it along side of xapi, though.

I think the good first step would be to get Remus support included in xl/libxl..
So contributions very welcome! :)

I had a play with this last night, but on the step to install the 686-pae
kernel it couldn''t find it in the repo and couldn''t install
the xapi
packages with the 3.0.0-amd64... I am thinking it''s probably because I
should have started with an x86 Squeeze, is that true?

Do you have an experimental line similar to the following in your
/etc/apt/sources.lst file?
deb http://ftp.uk.debian.org/debian/ experimental main

If so, do an apt-update and apt-cache search to make sure that the
package name didn''t change.

Thanks,
Todd

Can you give the details of the error you are getting installing which deb?

Thanks,
