Andre Przywara ed85c06853 KVM: introduce module parameter for ignoring unknown MSRs accesses
KVM will inject a #GP into the guest if that tries to access unhandled
MSRs. This will crash many guests. Although it would be the correct
way to actually handle these MSRs, we introduce a runtime switchable
module param called "ignore_msrs" (defaults to 0). If this is Y, unknown
MSR reads will return 0, while MSR writes are simply dropped. In both cases
we print a message to dmesg to inform the user about that.

You can change the behaviour at any time by saying:

 # echo 1 > /sys/modules/kvm/parameters/ignore_msrs
