Yes, based on my view that an external clocksource has to be used if TSC
is the primary local clocksource.
I will double check what the concern was about v10.
The change for xen-tscmode(7) needs to be redone, at least.
So before I spam you guys with any more variants, I better ask if any further attempt would fly anyway.
Olaf
