It was painful to maintain a patched kernel for it. KVM is included in mainstream kernel since 2.6.20. I personnally chose KVM as virtualization solution because I know it is in fact available in every Linux distribution. So if one fails, you can choose another, free, solution. But with 3.0 kernel, it will perhaps also become true for Xen...
