Okay, I've enabled intremap=no_x2apic_optout on the host kernel and didn't see much of a change in performance. I feel I should mention that the qemu process on the host consumes about 8-30% CPU (as shown in top) when the guest (Windows 10) task manager shows <1.0% cpu utilization. More often than

I just tried testing the patch. Initially, it seemed to work fine (log messages below). However, I am getting hard lockup of the host machine shortly after the vfio_region_setup related log lines print out to the screen. I would say that rougly 3 of the 9 VM startups resulted in a hard lock like
