This is bullshit.

KVM is buggy und very unstable. It´s NOT RECOMMENDED for production usage.

Xen is fully developed, fast and more reliable than KVM.
Thousands of companies are using Xen or Citrix XenServer and its super fast, easy to use and 100% rockstable!
The XEN PV Guest drivers are excellent in comparison with the KVM windows guest drivers. (after installing the 64 bit networking drivers with Server 2008 x64 > blue screen...).. I hate kvm.

@ Linus : Please merge xen as hypervisor into linux, right now !
