I didn’t see anything on the level VMware Converter, VCB, Patch Management of the guest, Dmotion over non-connected storage, or integration of 3rd party switches and CDP, or the Power integration. Of course, this is an outsider’s perspective.

Can you provide any specifics as to the particular features that are actually included in the XenEnterprise 4.0 beta? Thanks!
