I suspect you are attempting to fight a pre-determined losing battle. If
there are solid, specific, technical requirements that are missing from
your xen solution today, and are available from vmware today, then
continue to fight, but change tactics. Otherwise, just give up now :)

If you need specific solutions, then the best option is to ask for them,
potentially they are already available, you just don't know about them,
haven't considered that solution, etc. Address each requirement, one at
a time. I would expect that xen (as a small part of a virtualisation
infrastructure) would be capable of just about anything you could
require. Let us all know what you need, and someone else has probably
already solved it.
