====== QEMU ======
==== Redirecting monitor to unix socket ====
1. Run QEMU with the following options:

'' -monitor unix:/tmp/qemu-monitor-socket,server,nowait''

2. Connect using socat:

''socat -,echo=0,icanon=0 unix-connect:/tmp/qemu-monitor-socket''

You can also issue individual commands directly to that socket, e.g.:

''echo "info status" | socat - unix-connect:/tmp/qemu-monitor-socket''
