If you just want to disable any filtering from your VM networks, go to
Network -> vNIC profiles -> ovirtmgmt, Edit, under 'Network Filter' choose
"No Network Filter".

For more refined configurations, please see:

I guess that you can use a direct rule for allowing any traffic to the
nested VM.
As far as I know the nested oVirt is not working nice and it's easier
to test with a single VM with KVM.
