libvirt users - Aug 2015 - Do I need to enable qemu-ga's guest-suspend: hybrid/suspend-ram/disk/shutdown?

How do I "enable" qemu-ga on a guest to be able to (I think this means
have
a success-response:true) for: guest-suspend-hybrid; guest-suspend-ram;
guest-suspend-disk; and guest-shutdown?

At least I think that's my question.
http://wiki.stoney-cloud.org/wiki/Qemu_Guest_Agent_Integration shows these
same 4 as false, so I'm not sure if they're always supposed to be that
way.

My overall point is to be able to run dompmsuspend servo disk.  After
setting up qemu-ga as far as I have, it at least says:
====Domain <vmname> successfully suspended
====But,

Using libvirt 1.2.18 (-1 Arch) and QEMU git-master (2.4.0.r40384.2d69736).
pm-utils 1.4.1-6.  acpid 2.0.23-4

Installed using Q35 chipset.

"success-response":false has nothing to do with whether a guest-agent
command is enabled, but rather whether you should expect a response from
the agent itself when the command succeeds.  For these commands, the
answer is no, you do not get a response from the guest agent, because
the action performed by the guest has shut things down to the point that
it cannot reply; instead, to learn if the command was successful, you
must listen to the ordinary QMP monitor for an event notification
corresponding to the change in guest state.

Libvirt already handles this interaction correctly.

FYI this is a typo in the email -- the file properly uses "enabled"
not
"enables"

Ahh, OK.  Rats, was hoping I had found a lead to my "no matter what method
I try, I can't have a graceful shutdown/suspend of my guest VM's if the
host is shutting down/rebooting" problem.
