Thanks to this headsup, we finally know that not only Ubuntu has steered away from the dependency on Microsoft's partner Citrix. Red Hat is doing something similar now.

Ever since XenSource had been acquired we have repeatedly argued that it's yet another example of Microsoft (plus ecosystem) 'stealing' free open source projects from GNU/Linux.

Red Hat Takes Hypervisor Control Back From Citrix

Red Hat announced two important moves this week; open sourcing of Red Hat Network Satellite, and their own virtualization hypervisor oVirt. Open sourcing RHN Satellite is fundamentally about showing the industry Red Hat is still the keeper of the open source flame but the real strategic move is the development of oVirt. oVirt is built upon Kernel Virtual Mode, or KVM, which is virtualization built right into the Linux operating system, and has been maturing over the past two years. Until now Red Hat's virtualization strategy has been built around open source Xen, much like other players such as Oracle and Sun Microsystems.

When Citrix took over Xen, it created a sticky situation for vendors depending on the Xen open source software for their virtualization strategies.
