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?
If it's for debugging, you can use qemu without kvm. If you're only
interested in a few pages (and are proposing a solution based on that),
I don't think that can be done with EPT / NPT enabled so it won't be
something that'll be accepted upstream.
