Re: [Xen-API] Regarding Project Kronos: Problems faced and feedbacks

[Thomas Goirand <thomas@xxxxxxxxxx>]

Hi Deepak,

I'm the Debian Developer who helped with the packaging and who uploaded
XCP into Debian SID. I'm also working with XCP and OpenStack, and last
week, I did some tests with it, using only the packages from SID.

The packages are in good shape, but there's still few things to fix, like
having a python-xenapi package (already committed to the Git, but not
yet uploaded to SID), and have the OpenStack packages depend on it.

Now, let me reply to your questions.

I see no error here, but a *warning*, which is different.
The issue is that the repository isn't signed. I'm not sure
how to fix that in Launchpad, but for a custom private repo,
that's not so hard to do. Anyway, I believe you should just
ignore this warning.

Right, the new file really is /etc/xcp/inventory, and there's
nothing to touch in it. It's correct by default.

Right, the init.d script has been renamed to match the package name.

I'm not sure with the instructions on the wiki, but what I've written
in here works:

http://anonscm.debian.org/gitweb/?p=pkg-xen/xen-api.git;a=blob;f=debian/README.Debian;h=c342ef1829d0190ef764a9f8e259db6a60325d48;hb=57892b47dd730ea6e7a1db9e98a934122ebe0876

This will be packaged in the xcp-xapi package at the next upload.

Last, I would suggest you to try using plain Debian SID rather than
Ubuntu, since that's where the developments are done (Ubuntu just
imports what we do in SID).

Cheers,

Thomas
