[Libguestfs] [PATCH v2] launch: Error if you try to launch with too many drives.
v1 was here:
https://www.redhat.com/archives/libguestfs/2017-April/msg00268.html
v1 broke some tests because the guestfs_max_disks API isn't supported
by some backends, specifically ‘unix:’. This makes failure of
guestfs_max_disks non-fatal.
Rich.
