In order to build caml-stubdom, it must be explicitly enabled via
"configure --enable-caml-stubdom". The build process is failing due to
stubdom/ocaml.patch failing to apply. Since the patched file has been
modified in 2014 the last time, it seems nobody cares for caml-stubdom
since at least then.

Xen PV devices in QEMU can be created in two ways: either by QEMU
