How to connect to running qemu instance with qemu monitor

Prefer to do this is to connect to the QEMU "monitor" via a UNIX socket.

When you start QEMU, add the -monitor parameter as follows:

$ qemu-system-x86_64 [..other params..] -monitor unix:qemu-monitor-socket,server,nowait

$ netstat | grep qemu-monitor-socket
b07c1a8d21e459991 stream　　0　　0 b07c1a8d1de32c19　　0　　0 qemu-monitor-socket

$ socat -,echo=0,icanon=0 unix-connect:qemu-monitor-socket
QEMU 9.1.0 monitor - type 'help' for more information
