Hi Roger,
I tried to get some VMs running on
FreeBSD-12.0-CURRENT-amd64-20180802-r337160.
System is a Supermicro X9DRi-LN4F+ mainboard with dual Intel E5-2680v2
(ivy bridge).

When using xen-tools47/xen-kernel47, during boot of dom0, I only get the
error seen in the attached png ("d0v0 Triple fault").


When using xen-tools411/xen-kernel411, I can boot without problems, but
when running "xl create", neither a PVH nor HVM config work (see configs
and logs attached).
They both throw "libxl: info:
libxl_create.c:109:libxl__domain_build_info_setdefault: qemu-xen is
unavailable, using qemu-xen-traditional instead: No such file or directory"

Which doesn't make much sense to me, as PVH shouldn't use qemu at all?

The config files were put together following the documentation in
http://xenbits.xen.org/docs/4.11-testing/man/xl.cfg.5.html
which marks some of the keywords or syntax used in the FreeBSD handbook
as deprecated (i.e. 'builder' vs. 'type').

If I should do something different, or test a patch or something, let me
know. I'm super excited to see a recent Xen version ported to FreeBSD! :-)
