If your sharing a physical interface with both tagged and untagged traffic
they don't allow VM's on the untagged link. I believe this is because some
earlier versions of the bridging code in the kernel would allow pass the
tagged traffic to VM's located on the untagged interface. That being a
security issue.

Thanks, now I can use the eth0 to connect to the web-interface and
the
logical vlan network to use in a VM but I can't use the untagged VLAN1
in the VM. When I add a new logical network without VLAN tagging the
web-interface returns "Cannot have more than one non-VLAN network on one
interface."
When I create a logical network with taggged ID 1 I can't connect from a
VM to my VLAN1.
So I have to find a way to created the following networks:
- ovirtmgmt: without tagged vlan for managing -> works
- vlan1: without tagged vlan for the VM's to connect to my default
network -> currently no solution
- vlan10: tagged vlan with id 10 -> works
