Subject: qemu-iotests: redirect nbd server stdout to /dev/null
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=43421ea05f8dfe85dcbb2d4932730fe8cb74dbf4;p=qemu.git

qemu-iotests: redirect nbd server stdout to /dev/null

Some iotests (e.g. 174) try to filter the output of _make_test_image by
piping the stdout.  Pipe the server stdout to /dev/null, so that filter
pipe does not need to wait until process completion.
