With the introduction of Red Hat Enterprise 6 Beta, Red Hat has changed direction in their choice of virtualization: they have dropped Xen entirely in favor of KVM.
This is not entirely a surprise, since Red Hat bought Qumranet, a company active early on in KVM development.
What does this mean for us as administrators? This means that we will have to convert any Xen virtual machines to KVM machines if there is to be support from Red Hat. Alternately, support for Xen will have to come from Citrix. This means either internal costs (such as labor, downtime, etc.) to migrate from Xen to KVM or external costs in adding Citrix support of Xen to the costs of Red Hat Enterprise Linux.
With this in mind, even if we do not have Xen virtual machines, we need to learn a new virtual environment before we are called on to support it in-house. When the company calls on you to support a KVM virtual machine, you will be ready.
This is just amazing: did everybody coordinate this? Within the last three weeks or so, we’ve seen these releases come out:
Several of these were released on the same day, November 1.
What next? Am I really supposed to choose just one? Sigh. And I just installed OpenBSD 4.1 and Fedora 7, too – not to mention installing FreeBSD 6.2 not too long ago.
From all the talk, I’ll have to try Kubuntu again. So many systems, so little time.
I have been using OpenSUSE 10.3 (with KDE). I just love it – and I love the new menu format, too.
Update: Sigh. I should have known. Microsoft Windows Vista celebrated its 1st Anniversary on Nov. 8.
