[libvirt-users] How to config qga to support dompmsuspend

[Hong-Hua.Yin at freescale.com]

Hi,

I tried to run domsuspend command on my PowerPC board but failed. 
# virsh dompmsuspend sdk --target mem
error: Domain sdk could not be suspended
error: argument unsupported: QEMU guest agent is not configured


It seemed that support suspend-to-mem only from capabilities.

I read from some document about qemu guest agent but still don't know how to config it as daemon in guest domain.
