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.
