Make sure to state that the host system in the "Create a new image"

If the media is windows and guestfs version is less than 1.17.18
raise a Fatal Error. The versions below this have a bug and
inspect_os will fail if the HKLM\SYSTEM\MountedDevices registry key
is missing. This key gets deleted by Microsoft Sysprep

Before libguestfs 1.18.4 you cannot shutdown the backend and then
relaunch it
