Implementation notes:
I wrote out this numeric parsing logic for the version check to avoid a big regex. Not sure if it's worth it, LMK if you prefer and I'll just switch it back to the existing system.
Adding
has_watchdog_arg
everywhere looks a bit annoying, maybe better to just pass theQemu
in or something and then let architectures check whatever flags they like?Possibly we could just skip all this and use
-device
unconditionally, I have no idea when in QEMU's version history that became valid. In that case we can just merge s/-watchdog/-device #81 and delete this.
