<div dir="ltr">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.</div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Sep 4, 2015 at 9:47 AM, gregor <span dir="ltr"><<a href="mailto:gregor_forum@catrix.at" target="_blank">gregor_forum@catrix.at</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Thanks, now I can use the eth0 to connect to the web-interface and the<br>
logical vlan network to use in a VM but I can't use the untagged VLAN1<br>
in the VM. When I add a new logical network without VLAN tagging the<br>
web-interface returns "Cannot have more than one non-VLAN network on one<br>
interface."<br>
<br>
When I create a logical network with taggged ID 1 I can't connect from a<br>
VM to my VLAN1.<br>
<br>
So I have to find a way to created the following networks:<br>
- ovirtmgmt: without tagged vlan for managing -> works<br>
- vlan1: without tagged vlan for the VM's to connect to my default<br>
network -> currently no solution<br>
- vlan10: tagged vlan with id 10 -> works<br>
<br>
