If you want daemonized instances, and wish to use the monitor, then
rather than using '-monitor stdio', it'd be better to have it connect
to something like a UNIX socket, eg

   -monitor unix:/var/run/qemu/mysock,server -vnc localhost:1,password

Then, you can have a simple command line tool to send & receive
individual monitor commands via that socket.

Take a look at

  "3.10 VNC security"

  http://bellard.org/qemu/qemu-doc.html#SEC36

There's also some docs under

  "3.3 Invocation"

  http://bellard.org/qemu/qemu-doc.html#SEC10
