When creating VM from template, on a namespace labeled with primary UDN label, the VM creation wizard shows two interfaces instead of one on Network interface tab: one with 'Masquerade' binding and another one with 'L2bridge' binding.

It seems like merely UI issue since the YAML generated with single interface, as expected.

1. Switch to namespace that label with the primary UDN label
2. Go to VirtualMachines > create > from template > Fedora VM 
3. Click Customize Virtual Machine 
4. Go to Network Interfaces tab

Network Interfaces tab present two interfaces with name 'default', one with 'Masquerade' binding and another one with 'l2bridge' binding.

Network Interfaces tab to present single interface with name 'default' and binding 'l2bridge'

I customize the VM network interfaces in order to use the TP passt binding plugin.
