Re: [libvirt] [PATCH v2] Add ability to register callback for virCommand dry run

To allow for fault injection of the virCommand dry run, add the ability to register a callback. The callback will be passed the argv, env and stdin buffer and is expected to return the exit status and optionally fill stdout and stderr buffers. Signed-off-by: Daniel P.
