[Libguestfs] [PATCH 0/2] v2v: Add --print-target to display overlay and target information.

RHV was connecting to the VMware source in order to find out the virtual disk size of the source disk(s), duplicating logic that virt-v2v already provides. This makes that information available using a new ‘virt-v2v --print-target option’. Note in order to get all the information, this has to actually perform the conversion step, so it takes 30 seconds or so before we reach the point where the information gets printed. We could also add a more easily parsable version of this data ... Rich.
