KVM is included in the mainline linux kernel since 2.6.20 and is stable and fast for most workloads.

It is also available as a patch for recent Linux kernel versions and as an external module that can be used with your favorite distro- provided kernel going back up to 2.6.16, therefore including all latest versions for Enterprise Linux Distributions.
