(I see further discussion has obviated the need to deal with this,
but:)
You mean to patch trad to make a few more hypercalls to explicitly
create an ioreq server ? Would it have to register all of its memory
regions ? If it wouldn't, then the change to qemu-trad wouldn't be
too hard.
qemu-trad is fairly closely tied to the Xen releases so we wouldn't
have to support the old way for very long.
Ian.
