Last question:
anything I should know about logging in remotely (SSO)?

{"__name__":"login",
"parameters":[{"username":"user", =
"password":"secret"}]} \n=20

should work?

missing something.

Yes the newline character send a =E2=80=98\n=E2=80=99 at the end and the =
name key must be surrounded by two underscores like in the replies =
__name__ not name

    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.
