Not sure, have to dig into the xen code to figure.

Could be xen doesn't remember the page in the first place. They might let the illegal instruction fault handler patch the opcode. At least I vaguely remember some discussions about that.

Could be there isn't a interface to forgot the page. "reboot" in xen land is "destroy guest, restart it".

How do you unload a driver then?

What about kexec?

I'm glad we didn't do a hypercall page in kvm.

Sure, but later on, we may want to take advantage of kernel netback.

Agree. But right now I have more important stuff to worry about ;)

Still good to know what to expect later on.
