Hi I've been playing around with gbhv as part of getting into hypervisor research I'd like to appreciate the project it's well made and it pretty simplistic which helps my learning curve by a lot

I have a question I'm trying to extend its compatibility with a manual mapper and I know that it should work since there's isn't much SEH

However, as soon as I remove the driver unload routine I've had to implement more VM exit handlers for MSR R/W

the handlers are implemented correctly but then I'm getting an exception when restoring CR4 for disabling Virtual Machine Extensions
