Hi Frank,

Without the ability to control the networking devices in your vicinity and 
setup VLANs, what you're trying to do isn't supported via oVirt.

However, assuming you do have root access to your host, I can suggest a 
workaround:
* Create two dummy interfaces on the host, and give them static IP addresses. 
For example: 192.168.1.254/24, and 192.168.2.254/24.
* Create two networks (Non-VM) called One and Two and attach them to the dummy 
NICs.
* Create VMs with virtual NICs in network One, and VMs with virtual NICs in 
network Two. 
  You can give them static IP addresses and supply the host's dummy interfaces 
as gateways, or enable a DHCP server on the host.
* Enable routing on the host, and setup the appropriate rules so that he acts 
as a default gateway for all of the VMs, and that he forwards traffic 
appropriately between the VM networks.

unfortunately, using VLAN tagging is not an option for me,
because I'm not the maintainer of the network devices (and
my hosting provider won't configure VLANs for me).

Is there another way to get multiple networks in oVirt up
and running?

FYI: The main purpose of these internal networks is a test
environment for some VMs. Those VMs should be able to reach
each other and to have internet access.


Thanks
