What did you find not working? Did you really encounter anything not being solved by setting Permissive mode instead disabling completely?

What's the purpose of permissive ? if everything is allowed, what selinux is good for ? Instead of having something that run doing nothing, I shutdown it, and selinux is part of that generic policy.

What is a bad practice is switching selinux on and off. So my installation setup is done with selinux down and stay so for the whole server life of the server.

I never met a product that requisite selinux.

And more, I just have a look at your administration guide (http://www.ovirt.org/documentation/admin-guide/administration-guide/) and quickstart guide (http://www.ovirt.org/documentation/quickstart/quickstart-guide/). selinux is never declared as mandatory. There is just a few tips about the problem that one can have with selinux.
