It might be that the IOMMU has an errata and Xen refuses to enable it. Can you provide the serial output when you try to boot Xen + FreeBSD? You might have to add console="com1,vga" to your xen_cmdline (although AFAIK that's the default). The command line looks fine IMHO. > On the other hand I'm still not sure whether the hotplug patches > still need to be applied or not, I've checked them and I'd say that both > the kernel and xen-tools need to be patched, am I right? Yes, both series need to be applied. If you find issues applying them ping me and I can rebase them if needed.
