It is.  But unless you are planning to run the external virt-v2v tests --
which you cannot do because they contain proprietary Windows binaries
and are therefore not generally released -- you don't need to compile
the test harness.

You can either uninstall ocaml-libvirt entirely (and rerun
./configure) or modify the Makefiles to not include this directory.
