It's worth noting that Bytemark started out as and was for a very long time a Xen shop.

They started out with User Mode Linux actually, before Xen even existed.

Indeed -- and stuck with it for quite some time. They were trialling Xen for some time, but I don't think they ever deployed it on a terribly large scale. Certainly, my VM went straight from UML to KVM.

I believe the management tools for Xen (or lack thereof) were the reason for using KVM instead. None of my machines (I have 7 or 8) have ever used Xen.

Thanks for the catch, I had forgotten that they were a UML shop.

They were never a Xen shop, they trialled Xen with a few customers but never rolled it out. This blog post has more detailed info:

Funny, I did read that article a few months ago but had completely forgotten about it. It's a good read if you're into the virtualisation thing.
