Is that enabled for any particular reason? Or maybe a better question is, what is it that you're trying to do and what, if any, errors are occurring? E.g. in the first trace, it looks like you're advertising an Intel vCPU to the guest on top of AMD hardware. That can be made to work, but it's not recommended. Ignoring MSRs in that scenario is almost guaranteed to cause weirdness. -- You are receiving this mail because: You are watching the assignee of the bug.
