KVM is the feather in Red Hat Enterprise Linux 5.4

“Red Hat announced Wednesday the release of Red Hat Enterprise
Linux 5.4, a new major point update of the company’s popular
commercial Linux distribution. This version introduces official
support for KVM and marks an important milestone in Red Hat’s
gradual transition away from Xen.

“KVM, the Kernel-based Virtual Machine, is an open source
framework that brings native full virtualization to the Linux
kernel. It is primarily designed for the x86 architecture (though
others are supported) and takes advantage of processor
virtualization extensions. It has been part of the mainline Linux
kernel since 2.6.20 and has become the favored virtualization
solution of the upstream kernel community.

“”Because KVM is integrated into the Linux kernel, it takes full
advantage of the operating environment,” Red Hat explains in a blog
entry. “This includes hardware and application support. Hardware
and software certified on Red Hat Enterprise Linux 5 should be
transparently certified for virtual guests as well. System tools,
including management, SELinux security and Red Hat Network all work
in both physical, virtual, host and guest deployments.”
