The host needs to log the access in some way (trace-event, pr_err) with relevant information. And with the guest-side kdump you can rule out that it was a guest bug which triggered the access. And you learn what the guest was trying to do when it triggered the access. This also helps finding the issue on the host side (if it is a host-side issue). (Guest and host owner need to work together for debugging, of course).
