As I said on my reply to Boris, I would really like to have a more
generic way of doing this kind of per-domain verbosity level, but I
don't think it would be fair to ask Boris to implement this. Xen
likely needs a way to print issues with MSRs accesses in 4.15 on a
per-domain basis, so going for a MSR specific solution would be
acceptable given the time frame. I think Boris made a proposal for a
solution on another email, let me go look at that.

Thanks, Roger.
