[Libguestfs] [PATCH] v2v: Set DISKTYPE=2 in RHV and VDSM meta files

I was trying to find some documentation for this field and the best I could find is: https://github.com/oVirt/vdsm/blob/master/lib/vdsm/storage/constants.py What do the numbers mean? The comments in the file indicate that strings are valid too (eg. DISKTYPE=OVFS). Also this patch as written will affect -o vdsm mode too (another deprecated-ish mode where we write directly to the Storage Domain). I don't know if that's right or not. Rich.
