Checking guest memory pages changes from host userspace

["Passera, Pablo R" <pablo.r.passera@xxxxxxxxx>]

Hi list,
        I need to monitor some guest memory pages. I need to know if the information in these pages was changed. For this, I was thinking to mark the guest memory pages in some way (like write protecting them) so a page fault is generated. Then manage this fault inside qemu. Is there some API in libkvm that allows me to do this?

Thanks a lot,
Pablo
