I'm trying to set up supervision for a QEMU virtual machine on a machine that uses s6 and s6-rc for service management.
I currently have my QEMU configured so that it shuts down gracefully when the "system_powerdown" monitor command is executed. With s6, though, the only idiomatic way that I can get the supervision frameowork to shut down a long-running process is to send it a signal. I've verified that I can get QEMU to terminate by sending it a SIGINT, SIGTERM, or SIGPWR; but all of those just cause it to terminate, they don't send an ACPI shutdown request to the guest operating system. Is there any way to trigger the same "system_powerdown" mechanism by sending QEMU a signal? If not, can anyone suggest a way to add a signal handler that does that?
