Interesting … sorry, I had read the docs a while ago and my interpretation
at the time was that it didn't. I can try to get libvmi working, but
nonetheless I do want to figure out how to this with the Xen API itself if
at all possible, so I'd appreciate any help in doing so.

LibVMI works with PV guests and you can
I have, but libvmi doesn't fit my use case — it only works with Windows and
Linux HVM guests. I will need my application to work with PV and HVM guests
that are neither Windows nor Linux.
libvmi's implementation of this, `xen_get_memory()` in

from a guest given a guest address (for instance, reading RIP from the
guest CPU context and then reading the current instruction). I'm using
xenforeignmemory_map() to map the guest memory, but this function takes the
