[Libguestfs] [PATCH v3 0/6] launch: direct: Disable qemu locking when opening drives readonly.

[Richard W.M. Jones]

v2 -> v3:

 - I addressed everything that Pino mentioned last time.

 - It's tricky to get a stable run when multiple copies of qemu are
   involved, because the same cache files get overwritten by parallel
   libguestfs.  So I changed the names of the cache files to include
   the qemu binary key (size, mtime), which removes this conflict.
   This is in new patch 4/6.

Rich.
