When Red Hat announced its plan to focus on KVM, and subsequently acquired Qumranet, the startup that maintained the virtualization platform, it was clear that its implementation of Xen couldn’t survive much longer.
In Enterprise Linux (RHEL) 5.4 and 5.5 Xen and KVM coexisted, but the former is going to disappear in RHEL 6.0.
The first public beta of the new operating system in fact doesn’t have it anymore, according to ComputerWorld.
Quite interestingly, ComputerWorld also quotes Simon Crosby, the Citrix CTO of Datacenter and Cloud division, who said “Red Hat has not contributed to the Xen code base for several years”, also suggesting that Red Hat is now five years behind the market because of its decision to support KVM.
