By "posted interrupts" do you mean that they get delivered directly to the VM, bypassing the host? If so, then yes enabling AVIC does provide that behavior. With AVIC enabled (kvm_amd.avic=1), I do not see the counters in /proc/interrupts increment for passed-through devices. -- -Steven Walter <stevenrwal...@gmail.com> _______________________________________________ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
