Thank you for reply!
Im trying to send JSON-formated shutdown command to windows guest vm =
now. Here=E2=80=99s small script I=E2=80=99ve written to test that:
http://pastebin.com/usAYc7Ww

But still I get no reaction from ovirt agent. Surely I=E2=80=99m missing =
something.

  is there any documentation o oVirt guest agent =3Dommands?
  To be more precise: i need to pass commands to =3DVirt guest agent =
from
  hypervisor.
  Reading =3Dnfo works fine:

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

  {"applications": ["Python 2.7.12rc1", "SPICE Guest Tools",
=3DTotal
  Commander (Remove or Repair)", "Python 2.7 =3Dywin32-216",
"Microsoft
  .NET Framework 4.6.1", "Git =3Dersion 2.9.0", "WinRAR 5.40 beta 2
(32-
  bit)", =3DNotepad++"], "__name__": "applications"}
  {"__name__": =3Dhost-name", "name": "WIN7_32BIT"}
  {"__name__": =3Dos-version", "version": "Win 7=E2=80=9D}

Every =3Dommand has to be send as a whole JSON object and sent as line =
=3Derminated by a \n character

The =3Dommands available are currently not documented however.

{=E2=80=9C__name__=E2=80=9D: =E2=80=9Cname=E2=80=9D,=3D=E2=80=A6 args}

- name: =3Dhutdown
  parameters:
- =3Dimeout: optional integer (seconds)
=3D/span>- reboot: optional boolean
- =3Dessage: string

- =3Dame: refresh
  parameters:
- =3DpiVersion: optiona integer=20
        =3Dnbsp;   this defines what information can be =3Dxchanged

- =3Dame: hibernate:
  parameters:
- state: =3Disk 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-gu=3Dst-agen=
t/OVirtAgentLogic.py#L306 at the parseCommand =3Dunction
or just ask here :-)

  I'm unable to find how to send command (lets =3Day "shutdown") to =
agent?.
  echo "shutdown" | socat =
=3Dvar/lib/libvirt/qemu/channel/target/domain-20-
  win7_32bit/com.redhat.kvm-vdi.0  -
  Does=3Dnot seem to work
  Thank you for your help.
