How about a different approach? Query the supported MSRs
(KVM_GET_MSR_LIST or thereabout) and reset them (with special cases
for the TSC, and the old clock MSRs when the new ones are present)?
I didn't went that route because I was unsure that every one of them
would be resetable by writing 0 on it.
There are probably others. We should reset them correctly anyway.
It's probably done by generic qemu code so it works.
And if we are going to special case the most part of it, then there
is no point in doing it.
If you think it is doable to special case just the tsc, then I am fine.
I think if we have the following sequence
clear all msrs
qemu reset
kvm specific msr reset
Then we'd be fine.
Oh, and tsc needs to be reset to 0 as well - it isn't a special case.
