GuestAgent support

[tincboy]

I just notified that qemu is now supporting the guest agent idea,
http://wiki.qemu.org/Features/QAPI/GuestAgent

So if I want to use this functionality in Proxmox, what steps I should consider?
I can write the guest agent by myself but what configurations needed to be done in host?

guest agent is planed for soon.
It's more than an idea,the agent itself already exist in qemu git tree.

server side, you need to add chardev and virtio-serial port at vm start command line

 -chardev socket,path=/tmp/qga.sock,server,nowait,id=qga0 \ -device virtio-serial \ -device virtserialport,chardev=qga0,name=org.qemu.guest_agent.0"

then you need to use the qmp protocol to communicate with the guest agent.
current guest agent command are available here.

Thanks spirit,
What you mean by vm start command? can't we put these configs in /etc/pve/qemu-server/vmid.conf ?

I think It should works if you put them in "args:" parameter
