Hello,

I have been using Xen for many years now. I have mainly used it on Ubuntu and Debian, but I have also tried it on CentOS 5. Most of my machines have been installed a few years back. Then there seemed to be good packages for most distributions and a lot of nice examples on how to get it working.

Now that I am trying to install a new server with the latest version of my favorite distribution, I am having a lot of problems. Not just that Âthey have started using an annoying version of grub, but also because the packaged Xen kernel does not seem to work.

So, I would like to ask what is the future of Xen in the Linux distributions and which one should I start using as my Xen dom0?

Best regards,

This has been a popular discussion. I think Xen in Dom0 is over hyped. We don't have ESX in the kernel. Anyway a shift in thinking is in order. If you want to use "off the shelf Linux" you can use the CentOS5x series as Dom0 (and upgrade Xen using the gitco repos) or use Suse as Dom0. I think the future is just using a Xen Distro like XCP or Xenserver. The Dom0 is a "product" as apposed to being Linux with an added package. It would have been nice to have Xen in the mainline kernel and it still may happen but I predict it will only happen when it doesn't matter anymore. Call my cynical.

I'm probably migrating all of my CentOS/Xen 3.4 machines to XCP in the future.
