I bought a new motherboard for my wife's computer, making sure it (Gigabyte GA-P55-UD3) and its processor (Intel i5-650) supported both vt-x and vt-d. Recently I've read in a techno-blog that Xen is dead because of KVM. Suse ships Xen, and I'd intended to use it, but this guy speculates that Novell is only sticking with Xen because of its relationship with Microsoft; other distributions are already switching to KVM.
Is there a firm answer to the value of Xen vs KVM? I've done some preliminary reading, and both look good to my uninformed eye. Are there any present advantages to Xen due to suse's direct support in the distribution? Is there risk that I might have to dump Xen in a year and rebuild my system with KVM? Are these questions worth asking :-)?
My personal opinion is that KVM has the greater momentum so over time I expect it to gain over Xen. Today, KVM has for me one clear advantage: I can run it on my laptop without the need to run a hypervisor etc. Today Xen is the more mature version and if you have critical workload on your servers, I advise Xen.
