Hi,I have a bit of problem, cannot install FreeBSD/Xen on a bit older hardware. The hardware should support the minimal VT-D/IOMMU settings, required by Xen.

Does it happen in Xen or in FreeBSD dom0 kernel? I have Xeon E3-1234 but I run 11.2-STABLE with xen-kernel-4.7.2_9 for a very long time already. I also have: hw.pci.mcfg=0 machdep.hyperthreading_allowed=0 Marcin
