I'm having similar problems with xen on 11.1, AMD64, June 2017.
The OS runs fine, but installed xen from package, setup exactly
as per the handbook and get a kernel panic on two machines,
complaining about iommu not being enabled.

Machines are: a Sun X4170 to start, then  a Proliant DL380 G7
with E5630 cpu. Both have all the virtualisation options
enabled in the bios, but there are no options on either machine
  for iommu.

Have other machines running FreeBSD, an Atom pc running as a
nas box, a couple of other Intel based systems and a Sparc
machine running 10.2, with a shedload of packages built to try
and get  an X desktop running. Got as far as xvnc remote
desktop working, but still trying to get Firefox built.

Normally, everything works out of the box with FreeBSD , so has
this really been tested, or is xen just not mainstream ?. Trying
to find info on xen / FreeBSD brings up a load of sometimes
conflicting info. The xen site is no help either, with possibly
out of date / not in sync with handbook info.

FreeBSD is the escape plan from Solaris and zones, but need
zfs, jails and xen to make it all work. Any ideas ?...

Regards,

Chris
