It's not very critical, if you are using a released version of Xen.
In particular, if it builds, you're unlikely to go very far wrong.

NB though that (as you suggest from "built together") the Xen control
libraries that qemu uses 1. do not have a stable ABI until recently
(sorry) 2. do not have a stable interface to the hypervisor.

So unless you are using the very latest bits, you must rebuild when
you use a different Xen version.

Additionally, the qemu configure script works by determining the Xen
version (rather than by looking for individual features) and keying
everything off that.  So if you are using xen-unstable, you will find
that some qemu versions don't build.

Ian.
