When the upstream distribution provides it. I am not sure if it is on their roadmap. Of course, you could also use Xen 3.2 from XenSource, but that's not supported here.
Take care, Daniel

I was at a recent Linux convention and it seemed very likely that Xen is no longer Redhat's priority at all and would love to put KVM in it's place. The Redhat rep was very adamant about KVMs superiority over Xen and the amount of unnecessary work to integrate Xen into their kernels. Some day when KVM will actually do what Xen does (and do it reliably!) Xen may not be an easy option.

So are you saying we should start looking at using KVM instead? I've never seen it, nor used it, so how much different is it from XEN?

I personally like Xen even though it's a bit difficult sometimes. The reality is that there probably will be a "Linux Virtual Machine" and then there will be the other third party ones that you can run if you want to go through the trouble. Xen, VMWare, VBox etc.. are third party. KVM is and will be integrated into the OS and will be everywhere. The amount of work being done on it is frightening. However, I don't think KVM will ever do real paravirtualization as they only focus on CPUs with VT support built in. They do paravirtualize drivers but the rest is roughly equivalent to HVM in Xen. I don't use KVM in any production environment because it's not always stable. I don't use it in a development environment because it doesn't do everything I want. Both of these things will change in the future. Because of the way the KVM VMs are handled (as tasks) though I'm not sure if it will ever be very good at having one VM span multiple real pipelines. But then again I'm not sure how efficient Xen can accomplish this. I'm working on a white paper testing the capabilities and speed of the major VM technologies in various environments but I have several months of testing left before I will release it. I'll know more when I get more data.
