FYI Out of a different discussion [1] I happened to learn about a kernel side fix [2] which unbreaks this case. It still would help to get the qmeu change landed, but the crashing guest is no more crashing with this. Therefore I wonder if we should add a kernel task to backport that to the Focal kernel.
That being said, the issue there was a crash if you run SSBD without IBRS, was it a crash as well for you or was it a different symptom?
