Libguestfs can already do this for offline guests.  I'd suggest looking
into using that, rather than waiting for qemu's guest-agent to be taught
a new command for manipulating live guests.

There has been talk of adding a generic qemu guest-agent command for
spawning an arbitrary command, but no patches so far (in part because
libguestfs doing the same functionality for offline guests has been
sufficient).
