Yesterday it was announced that Xen support has been putback (“committed” in CVS/SVN speak) to Nevada. The source is available now and the SX:CE release of Build 75 will be coming soon. While we’re talking about Xen, this is being released as “xVM”, for the following reason:

The xVM hypervisor is based on the work of the Xen community. The name
‘Xen’ is a trademark with some restrictions, so we have chosen to use a
separate name to describe Sun’s hypervisor.

This is an exciting announcement and its the culmination of a lot of hard work on the part of Dr. Tim Marsland and the “Matrix Team”. Congrats to everyone involed! This really finally rounds out the Sun virtualization strategy as I see it, with LDOM’s, Containers, and now xVM, as in house innovative efforts, in addition to existing 3rd party support from partners like VMWare.
