Even as open source virtualization gains momentum in today’s IT world, Red Hat Enterprise Linux’s (RHEL) switch from Xen virtualization to KVM hypervisors can put IT shops in a fix during the hypervisor selection process. In such a situation, benefits from server virtualization can follow once the organization understands changes that such a move can bring about. We bring you a complete guide, which pools in resources across the TechTarget network to help you tackle the Xen virtualization versus KVM dilemma.

How
will KVM virtualization affect RHEL Xen users?
Our in-house IT expert has put together a comparison between Xen virtualization versus KVM hypervisor in this tip. The resource comprises a brief history and description of Xen hypervisor’s relationship with RHEL, alongside a list that details the benefits of KVM hypervisor’s use in RHEL. The difficulties you may face during the Xen to KVM migration is also discussed in this section.
Understanding Xen virtualization versus KVM architecture
Learn about Xen virtualization and KVM virtualization architectures in this open source virtualization software guide. It highlights differences between the features of these two architectures. If you want to opt for open source virtualization solutions, this section will be of good help in getting behind the scenes.
Face off: Xen virtualization vs. KVM Linux hypervisors
Xen or KVM? A direct comparison on various levels will help you weigh the pros and cons of opting for either of these server virtualization technologies. In this section, we note the number of areas in which the KVM virtualization hypervisor (introduced in 2007 with RHEL 5.4) differs from the much established Xen virtualization hypervisor (introduced in 2003 with RHEL 5.0). Questions about which of the two have better management tools in place, down time issues, and overall processing performance are answered in this segment.
