Thank you Lev for the clarification. We had been installing manually via th=
e ISO, but I had mis-read some other articles about using python to automat=
e the process.
I will pass on the notes around /S and your article to our internal windows=
team. Maybe they have some ideas around the cert store, or at the very lea=
st pass off the manual instructions to our NOC.
I appreciate the response,
Patrick

Hi Patrick,
First of all lets clear some misunderstanding here - you don't need to manu=
ally install Python.
The installation of oVirt WGT is fully self contained, and while the oVirt =
Guest Agent it includes is indeed programmed in Python, the version include=
d is converted using py2exe (check py2exe.org<http://py2exe.org/> for more =
details if it interests you) into a standalone executable (well, almost - j=
ust like Windows version of Python.exe, it depends on Microsoft Visual Stud=
io CRTL, but we install it during the installation of the oVirt WGT).
Now about the automated installation. Generally we support silent installat=
ion of oVirt WGT.
You just need to supply /S command parameter to the installer.
However there is a catch - unfortunately Windows will popup warning message=
s due to the fact that the drivers supplied are non-WHQL'd. That is because=
the drivers are signed by Red Hat, Inc. and not by Microsoft certificate.
This is a security feature of Windows OS itself, and there is not much we c=
an do about it right now.
The side effect of this is that you need to manually approve the drivers in=
stallation for each driver, or choose to trust all drivers from Red Hat, In=
c., and then no more popups will show up. Unfortunately, you still need to =
do this manually at least once, and you can't pre-approve Red Hat, Inc. to =
make this process automated. For more information on installing oVirt WGT y=
ou can check this article: http://community.redhat.com/blog/2015/05/how-to-=
install-and-use-ovirts-windows-guest-tools/ by yours truly.
There is a workaround though, and it's to create a program that will automa=
tically approve such unsigned drivers dialogs. It's relatively easy to prog=
ram with i.e. AutoIt scripting engine (check: https://www.autoitscript.com/=
site/autoit/ ), which is free (like in free beer, but unfortunately not as =
in freedom because source code for it is not supplied). Note that you must =
be quite careful with that, as by doing so you basically disabling the secu=
rity mechanism that Microsoft had put in place for a reason, and potentiall=
y you may unintentionally install other non-WHQL'd drivers - if the install=
ation attempt for these other drivers will be made while your auto-approver=
program will run.
Thanks in advance,
Lev Veyde.
