Note your spelling...

and compare it to here.  There is no guest_ping command, only
guest-ping.  It's a bug in libvirt that guest-agent-command doesn't
output a useful error message when attempting to run a non-existing
command, but you'll never hit that bug if you pass valid commands to the
agent in the first place.
