Citrix Systems is acquiring XenSource, whose founders helped develop the open-source Xen hypervsior, for USD 500 million in a move that caps a significant week in the development of virtualization technology. The XenSource acquisition, which both companies announced Aug. 15, comes just a day after VMware, which has long been the dominant player in the x86 virtualization market, announced an initial public offering of 33 million shares of stock. By the end of its first day of trading, the company's stock closed at almost USD 51 a share.

KVM *is* the right *technical* solution for opensource. Xen is a bloated hack that has its interest in the times where there was no hardware support for virtualisation (VT/SVM). Now it's just overcomplicated.
Actually, Xen is not just about the hypervisor, as this one is useless without the Dom0... until they reinvent the wheel and reimplement all the drivers and FS support inside the hypervisor. If you crash Dom0 then your machine is dead. Talking about stability, security and strong isolation? Try to read about DomU to hypervisor and Dom0 communications...
KVM is about to catch up with Xen after only 1 year of developpment (it *does* support SMP) and far less ressources. Because it's design is clean.
And no, Microsoft Virtual Server is not working like KVM, not at all (hint, VT/SVM)...
