Subject: write protect the guest memory page from guest access

Hi all,

i want to set write protect (if guest try to write access, cause
exception) for a guest memory page. Assuming i know the gva of the
page, how do i achieve this? Is there any existing KVM function that
can help do it?

Thanks,
Sheng
