This commit adds a flag called 'control' to the '-monitor' command-line option. This flag enables control mode. The syntax is: qemu [...] -monitor control,<device> Where <device> is a chardev (excluding 'vc', for obvious reasons). For example: $ qemu [...] -monitor control,tcp:localhost:4444,server Will run QEMU in control mode, waiting for a client TCP connection on localhost port 4444. TODO: Update manpage.
