Hello,
I'm writing an application that can read/write guest memory, and as part of
that I need to check whether the page being manipulated is
readable/writable by the guest itself. Does Xen have an API that would
allow me to read the flags of an arbitrary page on a guest, given either
its address

Thanks! Sorry, I should have been more specific - I do indeed mean the
regular guest PTEs (and I'm using PV guests which as I understand don't use
EPT anyway). So, it seems I'll have to write my own code for this. I'll
take a look at libvmi's implementation; if anyone knows any other libraries
