is there any documentation o oVirt guest agen= t =3D commands?
To be more precise: i need to pass commands to = =3D oVirt guest agent from
hypervisor.
Reading = =3D info works fine:

socat =3D /var/lib/libvirt/qemu/channel/target/domain-20-
win7_32bit/com.redhat.serial.0 -

{"applications": ["Python 2.7.12rc1", "SPICE Guest Tools", =3D "Total
Commander (Remove or Repair)", "Python 2.7 =3D pywin32-216", "Microsoft
.NET Framework 4.6.1", "Git =3D version 2.9.0", "WinRAR 5.40 beta 2 (32-
bit)", =3D "Notepad++"], "__name__": "applications"}
{"__name__": =3D "host-name", "name": "WIN7_32BIT"}
{"__name__": =3D "os-version", "version": "Win 7=3DE2=3D80=3D9D}

Ever= y =3D command has to be send as a whole JSON object and sent as line =3D terminated by a \n character

The =3D commands available are currently not documented however.

{=3DE2=3D80=3D9C__name__=3DE2=3D80=3D9D: =3DE2=3D80= =3D9Cname=3DE2=3D80=3D9D,=3D =3DE2=3D80=3DA6 args}

- name: =3D shutdown

parameters:

- =3D timeout: optional integer (seconds)

=3D - reboot: optional boolean

- =3D message: string

- =3D name: refresh

parameters:

- =3D apiVersion: optiona integer

=3D this defines what information can be =3D exchanged

- =3D name: hibernate:

parameters:

- state: =3D disk or mem (default is disk if not specified)

if you need more you can look here: https://github.com/oVirt/ovirt-guest-agent/blob/master/ovirt-g= u=3D est-agent/OVirtAgentLogic.py#L306 at the parseCommand =3D function

or just ask here :-)

I'm unable to find how to send command (lets = =3D say "shutdown") to agent?.
echo "shutdown" | socat =3D /var/lib/libvirt/qemu/channel/target/domain-20-
win7_32bit/com.redhat.kvm-vdi.0 -
D= oes=3D not seem to work
Thank you for your help.
