Libguestfs supports passing an ISO image as a source of virtio windows drivers to v2v. That support, however, looks too heavy-weight: in order to access those drivers, a separate guestfs handle is created (and thus a new emulator process is started), which runs until v2v completes. This series attempts to make it simpler and lighter-weight, by making the relevant code more local, and by hot-adding the image into the main guestfs handle.
