To exit the guest system without GUI, using stdio redirected to the terminal, login as a root (user: root, password: root) and shutdown the system (wait after that for a while): # GuestĢ.

To get them, see Early boot messages in the host terminal below. You will not see any early boot logs in the host's console.nographic does the same as '-serial stdio' and also hides a QEMU's graphical window. nographic qemu-system-x86_64 -nographic wheezy.qcow2 You will see a welcome string after a successful boot.

Now I've got a pretty decent collection of working recipes to tune up a QEMU guest, so I decided to organize all that stuff here, and it could be definitely useful for anyone else. While struggling to automate QEMU guest (communicate and control with the shell scripts), I faced with a lot of incomplete, partially working solutions around the internet.
