[Libguestfs] [PATCH v2 0/1] p2v: avoid connecting to ourself while probing qemu-nbd

[John Eckersberg]

Changes since v1:

- Set probing source port to be nbd_local_port+1 instead of always
  using 50124 to deal with multi-disk scenario.

- Set SO_REUSEADDR on client socket to avoid issues with old
  connections in TIME_WAIT.

I've been running this for a few hours now using the updated
multi-disk test and haven't seen any problems.
