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.
