[Libguestfs] [PATCH v3 00/12] v2v: Change virt-v2v to use nbdkit for input in several modes.

v2 was posted here: https://www.redhat.com/archives/libguestfs/2019-July/msg00115.html This also has links to earlier versions. v3: - The 01/11 patch in v2 included a bunch of unnecessary plus one necessary change to how input_password is passed around. I moved the necessary change into the final patch (implementing SSH password authentication) and dropped the rest. - The 01/11 patch in v2 contained a trivial whitespace fix which unfortunately caused git to make the patch much larger than it needs to be. I split this trivial change out into a separate patch for easier review. - Some trivial grammar corrections in comments. It's best to view patch 02/12 with the ‘-w’ option to make it slightly easier to see what's going on. Rich.
