Hello Ed.

I found another way to solve the problem.
But I do not know if it's the right way :(
So I decided to ask a question here. But none of the gurus answered.


# mkdir ~/packages
# cd ~/packages
# wget 
http://ftp.us.debian.org/debian/pool/main/o/ovirt-guest-agent/ovirt-guest-agent_1.0.13.dfsg-2_all.deb
# apt-get install gir1.2-glib-2.0 libdbus-glib-1-2 libgirepository-1.0-1 
libpango1.0-0 libuser1 python-dbus python-dbus-dev python-ethtool python-gi 
qemu-guest-agent usermode
# dpkg -i ~/packages/ovirt-guest-agent_1.0.13.dfsg-2_all.deb

# systemctl restart ovirt-guest-agent.service
# systemctl status ovirt-guest-agent.service

* ovirt-guest-agent.service - oVirt Guest Agent
   Loaded: loaded (/lib/systemd/system/ovirt-guest-agent.service; enabled)
   Active: failed (Result: exit-code) since Wed 2018-01-03 22:52:14 MSK; 1s ago
  Process: 23206 ExecStart=/usr/bin/python

  Process: 23197 ExecStartPre=/sbin/modprobe virtio_console (code=exited, 
status=0/SUCCESS)
 Main PID: 23206 (code=exited, status=1/FAILURE)


As we can see, the service does not start.
In this case, the error in the log 
(/var/log/ovirt-guest-agent/ovirt-guest-agent.log) will be different:

MainThread::INFO::2018-01-03 
22:52:14,771::ovirt-guest-agent::59::root::Starting oVirt guest agent

    self.vio = VirtIoChannel(config.get("virtio", "device_prefix"))
  File "/usr/share/ovirt-guest-agent/VirtIoChannel.py", line 162, in __init__
    self._stream = VirtIoStream(vport_name)
  File "/usr/share/ovirt-guest-agent/VirtIoChannel.py", line 143, in __init__
    self._vport = os.open(vport_name, os.O_RDWR)
OSError: [Errno 13] Permission denied: '/dev/virtio-ports/ovirt-guest-agent.0'

As a workaround for this problem, I use this:

# cat /etc/udev/rules.d/55-ovirt-guest-agent.rules

SYMLINK=="virtio-ports/ovirt-guest-agent.0", OWNER="ovirtagent", 
GROUP="ovirtagent"

refresh udev:

# udevadm trigger --subsystem-match="virtio-ports"


# systemctl restart ovirt-guest-agent.service
# systemctl status ovirt-guest-agent.service

* ovirt-guest-agent.service - oVirt Guest Agent
   Loaded: loaded (/lib/systemd/system/ovirt-guest-agent.service; enabled)
   Active: active (running) since Wed 2018-01-03 22:54:56 MSK; 6s ago

           L-23255 /usr/bin/python 
/usr/share/ovirt-guest-agent/ovirt-guest-agent.py

Now the service is working.
But I do not know if it's the right way :(
