Can someone please explain what kvm.ignore_msrs=1 does?

[AntaresUK]

and whether it is a good idea to add this in to the flash boot params

I was reading something about this helps geforce experience to work correctly in a vm

My understanding is you should only enable it if you actually have a problem and it may or may not work.

The only time that I could have needed it was when windows 1803 fails to update (didn't realise it was related until later) but I managed to work around it using a different method.

 

So I don't think it's about "work correctly" but rather work vs crash sort of situation.
