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.
