Our entertaining friends at The Register have a nice write-up on Cassatt's recent announcement to partner with XenSource. The author is complimentary, despite feeling bogged down in "the morass of marketing hype surrounding the virtualization market." :-)

Plans are for Cassatt Collage Cross-Virtualization Manager (XVM) to support XenEnterprise 3.0 in the next release of the XVM product. (See our XVM doc page.) Cassatt will offer a pilot program for customers interested in early access to XVM support for XenEnterprise. (XVM with support for VMware is now generally available.)
