To achieve that all you need to do is create a template of the desktop
base vm, make sure the vm type is set to desktop. Afterwards just create
new vms from that template. As long as the VM type is set to desktop
each new VM will use a qcow overlay on top of the base image.
Taking this a step further you can then create VM pools from said
template, allowing users to dynamically be assigned a new VM on login.
Granted pools are usually stateless, so you need to have network file
storage. We use pools for windows 10 VDI instances, where we use sysprep
to autojoin the new pool vm to the domain where redirected folders are
already setup.
For VDI only use spice protocol. By default we found spice to be semi
lackluster, so we do apply custom settings and we have recompiled spice
on both servers and clients with h264 support. This is not 100%
necessary, but makes things like youtube much more usable. We have also
backported some audio patches to KVM. CentOS 8 should resolve a lot of
these customizations that we've had to do.
As far as updating, pretty much. We create a VM from the template,
update it, then push it back as a new version of the template. The pools
are set to always use the latest template version. Users have to log
out, then back in to the VDI system in order to get the new image as
logging out will destroy the users current instance and create a new one
on log in.

Hi Alex, thanks for answering.
I am approaching and studying oVirt in order to propose the solution to a customer as a
replacement for a commercial solution they have now.
They only need Desktop virtualization.
Sorry for the silly question, but I can't find a way to deploy a VM (template) to
users as a "linked-clone", meaning that the users' image still refers to the
original image but modification are written (and afterwards read) from a new location.
This technique is called Copy-on-write.
Can this be achieved with oVirt?
Then, what is the Best Practice to update WIndows OS for the all the users? Currently
they simply "check-out" the Gold Image, update it and check-in, while all users
are running...

yes, we do. All spice, with some customizations done at source level for spice / kvm
packages.

Is there anyone who uses oVirt as a full VDI environment? I would have a bunch of
questions...
