Expecting some heckling at the use of xen_overlay_singleton. What is the best way to do that? Using qemu_find_recursive() every time seemed a bit wrong. But I suppose mapping it into the*guest* isn't a fast path, and if the actual grant table code is allowed to just stash the pointer it gets from xen_overlay_page_ptr() for later use then that isn't a fast path for device I/O either.
Nah, it's fine. However I'll reply to patch 2 as to how to handle Xen vs. KVM mode.
