The callers are probably too varied to find a common way to do that (multiply with different user space tools). At least for some cases, the guest will be terminated in the near future anyway: For example, on s390 a NULL bus will cause an error to be propagated through KVM_RUN on the next guest->host virtio notification, which will cause qemu to terminate the guest. This situation is not ideal, but this is probably the most reasonable approach.
