Virtualization technology has long found a home in Red Hat's Fedora community Linux distribution. Ever since Fedora 4 emerged in 2005, virtualization technologies have continued to advance in the distro and that remains the case with the upcoming Fedora 13 release set for later this month. Unlike Fedora's early virtualization features, which all leveraged the Xen open source technology, more recent Fedora releases have relied on KVM. New KVM performance and scalability features for virtualization will debut in Fedora 13 that will help to push the envelope for large-scale virtualization deployments.
