Re: [Xen-users] Choosing Debian or Ubuntu as dom0

Hi all,

I need to set up three hosts as Xen dom0. I'm quite familiar with
Debian-type distributions, i.e. Debian and Ubuntu. I'm wondering which
distro is better suited for a dom0 system. In particular, I haven't been
able to find Xen 4.2 packages for neither Ubuntu Precise nor Debian.
It would be nice to have XCP working, but I noticed that the Xen wiki
recommends switching to Debian SID. However, I'm quite reluctant to run
an unstable distro on a production machine.

Summary of my questions:

* Is there a way to get Xen 4.2 in either Ubuntu or Debian
(not-unstable) without compiling from source?
* Which distro has better Xen support *in the repository*?
* Is there a way to get XCP working in either Ubuntu or Debian
(not-unstable)?
* Are the improvements from 4.1 to 4.2 good enough to make the trouble
of self-compiling (in case there are no packages) worthwhile?

Thanks for your insight!
Cheers, Andreas.

Hello,

I would take Debian Squeeze. At the end it is a question of which you like more. The compilation of Xen 4.2 is very simple and discribed in the Wiki. You can do this in a chroot to prevent installing all needed packages in the production system itself. The deb make target is very useful this will create a deb package of the Xen distribution so you can simple install and uninstall the core components very easy, you just will need to install a few additional libs over apt/dpkg like libjpeg because they are needed for the QEmu Backend but not a dependency of the created deb package. Make sure that you made the in the wiki mentioned configfix that everything is installed on the correct place (--install-layout=deb)

For nativ Dom0 support in the kernel which is not given in the normal squeeze Repos (2.6.32 kernel) you can use 3.2.0 from the backports repo (http://backports.debian.org).

Best Regards
