Would that be broken or not working ? Are you sure it's VT-d and not VT-x what you have enabled in the BIOS? Looking at the details of your CPU: https://ark.intel.com/content/www/us/en/ark/products/41447/intel-core-i7-930-processor-8m-cache-2-80-ghz-4-80-gt-s-intel-qpi.html VT-d is not listed in 'Advanced Technologies'. For example looking at a newer model: https://ark.intel.com/content/www/us/en/ark/products/149091/intel-core-i7-8565u-processor-8m-cache-up-to-4-60-ghz.html You can see VT-d listed in 'Advanced Technologies'. > I think I have used Xen a bit older version on Debian some time back if Im not wrong, on the same hdw.

Could it be something changed regarding Xen and iommu or ? Linux dom0 would likely be in PV mode (note the missing H), which doesn't require an iommu. OTOH FreeBSD only supports PVH dom0, which does require an iommu. Roger.
