This week the rumours about XenSource being swallowed by Citrix were increasing.

So it wasn’t a big surprise that Citrix today annouced that they signed an agreement to acquire XenSource a leader in enterpise-grade virtual infrstructure solution as stated at the website of Citrix.

With this move it will probably integrate XenSource into its "Desktop Server" product. It would’t surpise me that in a way the virtualization part of Desktop Server will develop in a way that it will favour the XenSource technology. With this move Citrix definitely strenghtens its position in the virtualization market.
