I can try this.

I can run a dom0 with Xen 4.8 and 4.9 domU, I already have the xen-diag
for it (so confirmed the patch in this bug report builds ok, we should
include it for stretch, it's really useful).

I think it's mainly trying to get a domU running with various
combinations of domU kernel, number of disks and vcpus, and then look at
the output of xen-diag.
