[pve-devel] [PATCH] add qemu guest agent client

[Alexandre DERUMIER]

just tested with -chardev qga_proxy,id=qga0

chardev: backend "qga_proxy" not found

so it's not implemented yet.
(I don't know if it's on the qemu roamap, I didn't find any info)

So Do you need to implemented the current procotol ?
(We need guest agent to freeze filesystem for snapshots

Oh I miss that ! 

" 
When QAPI-based QMP is available (somewhere around the QEMU 0.16 timeframe), a different host-side invocation that doesn't involve access to the guest agent outside of QMP will be used. Something like: 

qemu \ 
... 
-chardev qga_proxy,id=qga0 \ 
-device virtio-serial \ 
-device virtserialport,chardev=qga0,name=org.qemu.guest_agent.0 
-qmp tcp:localhost:4444,server 
" 


So we just need to reuse qmp socket. 
Is it already implemented ? (wiki is old, qemu 0.16....). 

I'll do some tests

Documentation states that we can do all those thing via qmp in future! So why 
do we want to add all that code now?
