People who use discovery tools are probably setting up a migration

BTW, it might be neat to introduce a qemu command line that runs a
monitor command and exits without creating a VM. We could then
introduce a info cpucap command that dumped all of the supported CPU
features.
Someone setting up a migration cluster would then run qemu -monitor
command="info cpucap", collect the results, compute an intersection,
and then use that to generate a -cpu flag. In fact, providing a tool
that parsed a bunch of those outputs and generated a -cpu flag would
be a pretty nice addition.
