"That's a question that Linux vendor Red Hat (NYSE: RHT) is aiming to address with today's release of Red Hat Enterprise Linux (RHEL) version 5.4 -- the first deliverable in the company's new enterprise virtualization effort that revolves around the open source KVM hypervisor.
"With RHEL 5.4, Red Hat is now including KVM as the basis for enterprise virtualization, though it is still supporting the Xen hypervisor that debuted with the release of RHEL 5 in 2007.
"As a result, Red Hat isn't abandoning Xen, but it isn't betting the future of Linux virtualization on it, either. Instead, Red Hat believes its future is with KVM -- and with the RHEL 5.4 release, the company is aiming to get enterprise customers to start thinking similarly."
