At several places the "difficulties" are mentioned. Is there some place
that these are listed or discussed in more detail?
Thanks

The difficulty is that Xen uses a Mach-like message passing system to
communicate information like DomU configuration. This requires kernel
threads to be operational early on in the startup of the DomU kernel,
much earlier than what FreeBSD allows. My attempts so far to allow
xenbus to synchronously retrieve its devce configuration instead of
relying on asynchronous messages has been unsuccessfull.
