Thanks.

Actually, the regular kfreebsd d-i images should work okay for a Xen
HVM-mode domU.  kfreebsd-10 should additionally be able to use PV
drivers in this mode out of the box, I think.

The "-xen" flavour kernels are only needed for a Xen PV domU, or for
kfreebsd-9 it may have run a little faster due to having PV drivers
(whereas generic kernels didn't).

I think Xen PV domU are becoming obsolete, with modern host hardware
typically supporting AMD-V / Intel VT-x now, or otherwise being very
slow/outdated for this task.

For the jessie release, I don't think new d-i images for Xen PVM will be
worth it.  Perhaps even the "-xen" kernel flavour will be dropped unless
sufficient demand can be shown for it.  Its existence may actually be
confusing if the generic kfreebsd-10 images are suitable.
