    @swill Yes, running this in production on our cloud
    
    I just started an Instance and the Agent (backport to 4.8, clean merge) produced this

    </channel>
    <input type='tablet' bus='usb'/>

    ```
    
    There you see this channel added:
    
    ```
    <channel type='unix'>
    <source mode='bind' path='/var/lib/libvirt/qemu/i-2-25-VM.org.qemu.guest_agent.0'/>
    <address type='virtio-serial'/>
    <target type='virtio' name='org.qemu.guest_agent.0'/>
    </channel>
    ```
    
    In the Ubuntu 14.04 the Guest Agent is running:
    
    <pre>
    root@vhosting-relay:~# ps aux|grep qemu
    root      2789  0.0  0.0  17468   700 ?        Ss   22:19   0:00 /usr/sbin/qemu-ga --daemonize
-m virtio-serial -p /dev/virtio-ports/org.qemu.guest_agent.0
    root      2890  0.0  0.0  10460   908 pts/6    S+   22:20   0:00 grep qemu
    root@vhosting-relay:~#
    </pre>
    
    From the HV I can send commands through libvirt:
    
    <pre>
    [root@n06 ~]# virsh qemu-agent-command i-2-25-VM '{"execute":"guest-ping"}'
    {"return":{}}
    
    [root@n06 ~]#
    </pre>
    
    I also re-started a Console Proxy which has a additional channel, that works as well:
    
    ```
    <channel type='unix'>
    <source mode='bind' path='/var/lib/libvirt/qemu/v-215-VM.agent'/>
    <address type='virtio-serial'/>
    <target type='virtio' name='v-215-VM.vport'/>
    </channel>
    <channel type='unix'>
    <source mode='bind' path='/var/lib/libvirt/qemu/v-215-VM.org.qemu.guest_agent.0'/>
    <address type='virtio-serial'/>
    <target type='virtio' name='org.qemu.guest_agent.0'/>
    </channel>
    ```
