Not sure about through the UI, but this can be down with the default
network scripts. I have 18 nodes in a cluster each with 2 nics. The nics
are bonded together as bond0 and 3 vlans are used (well counting default)
and one for management (vlan 1), one for private traffic (vlan 2), and
public traffic (vlan 8). Ovirt picked up the network config without any
issues and now I can assign VMs private and or public.

I have been looking at the different possible network configurations
shown at http://www.ovirt.org/wiki/Vdsm_Network and trying to work
out how to achieve the second topology ( bridge over vlan over nic
). I can see that it is possible to assign a logical network to a
physical network on a node but how can you add more than one as this
is a dropdown menu? My nodes have two NICs, one of these is for the
management network but I could like to have a number of logical
networks (with different VLAN tags) connected to the other NIC.

Very simple
1. create your logical networks with vlan tags in the data centre
2. assign those networks to the relevant cluster
Now, assuming we are going to assign network X with tag 100 and network Y with tag 200 to
eth0 on a host:
Edit eth0 on the host - assign network X to it
see how eth0.100 gets created and the X network attached ot that tagged interface
Edit eth0 again, assign network Y
see how eth0.200 gets created and Y is attached
repead for additional tagged networks

Yes, we can do these manually if we are the master of the system
administrator. But I think we should provide a UI to the user and VDSM
management API in the backend. Also, it is a quite a challenge to
assign the VMs in different host to the same vlan.

Yes, we can do these manually if we are the master of the system
administrator.
This is the administrator's job to configure hypervisor hosts.
But I think we should provide a UI to the user and VDSM
management API in the backend.
Simple users changing Host networking? I think it's not a good idea.
Also, it is a quite a challenge to
assign the VMs in different host to the same vlan.
Maybe you wasn't clear enough. The settings I mentioned are talking about configuring
__hosts__, not VMs.
All the hosts in a cluster must have configurations to see all the logical networks
assigned to that cluster. This way, a VM that uses a specific network can easily migrate
between hosts without losing networking
