Hmm. It would match what we have for qemu-monitor-command; on the other
hand, it differs from what we have for normal events (libvirt events are
fine on a read-only connection). I guess an argument in favor of
requiring write privileges is that qemu may expose details in its events
that are better left internal to libvirt (that is, libvirt has a chance
to scrub details before handing information to read-only guests, but
with raw event handling, there is no scrubbing). And it's always easier
to relax things later than it is to add read-write restrictions later
and break existing callers that had grown used to read-only.

Copy-and-paste, all the way! I'll clean it up.
