... The question is what does Xen offer that KVM cannot provide? Looking at the slides of the KVM Forum 2011 (http://www.linux-kvm.org/page/KVM_Forum_2011) there seem to be many interesting improvements in the pipeline so at some point the question really is why hold on to Xen at all when there is not real reason to? ...
For me, it isn't "why hang onto Xen?", it's "why convert my 18 virtualization servers?" Most of my servers are remote. I have 8 physical locations. Each location has a spare server for redundancy. To change to anything else, I'd need a compelling reason as the time and effort and, potentially, travel expenses would be significant.
Looking at scheduled CentOS 5 EOL, I can get other things done before having to tackle major upgrades. When I do start working on my next iteration of my system design, I'll be considering all hypervisors.
