Re: [Libguestfs] [PATCH] lib: direct: Set QEMU_AUDIO_DRV=none when testing schema.

Schema parsing was failing with errors such as: libguestfs: QMP parse error: '[' or '{' expected near end of file (ignored) This happened because the QMP command was actually completely failing and never printing a result at all. This happens because the qemu audio driver can't be set up without a console. We can suppress this by setting the environment variable QEMU_AUDIO_DRV=none, which is the same thing that libvirt does, and also the same thing that we are already doing when launching the real appliance subprocess.
