hi all,
if gpte in guest table was set write protection , the corresponding spte in shadow will set be write protection. so any operation in guest trying to
modify guest page will generate page fault to stop the opetation except on condition that the guest set wp bit in cr0. so my question is, how to make sure the guest is not able to modify specified page,considering the condition that wp bit in cr0 will be set to 0?
thanks.

the last thing we need more of is less effort
