Actually, I'm not sure I can add an element here since the size of VhostUserPayload.memory.regions is defined as fixed to VHOST_MEMORY_BASELINE_NREGIONS, which is 8. It seems plausible that if this is a standard expected size, that adding another region could violate some assumption in the back-end implementation. However, I should be able to avoid the issue by combining the vring region with one adjacent in the IOVA space when sending to the back-end.
