Nice.  Just today, I hit a bug where I wish we were caching qemu
capabilities better, and by filtering things into a common entry point,
I'm hoping it makes future edits able to take advantage of that one
location, rather than chasing down multiple callers.

At any rate, this patch looks correct:

ACK.
