I think the appropriate place is the README in a similar place to the
build dependencies. I suppose it needs to be worded as semioptional to
account for the fact that we supply one which is certainly OK.

Since, as you say, qemu-xen was preview in 4.2 I don't think backporting
fixes to it would be appropriate anyway, regardless of the support
