Using a fixed port number means multiple users won't be able to run this
in parallel. That it's only open for a short time actually makes the
issue a bit worse as it's hard to understand just why the test failed
intermittently.
Is there a way to have qemu-nbd use a random port and print the port
number?
Good idea. We can just let the script generate a random port;
$(($RANDOM+32768)) should do the trick.
