<p>So far I have come up with a workaround - again not very elegant - but at least it starts up the container so that it gets a DHCP IP address from my tagged VLAN 10. I just use this little script to start it up - instead of using "lxc start lxdora7a" I use
my script "lxdora7a.start" which contains this:</p>
<p><br>
</p>
<p></p>
<div>lxc start lxdora7a<br>
sudo ovs-vsctl set port lxdora7a tag=10<br>
sleep 2<br>
lxc list<br>
<br>
which reliably starts up the container and gets it an IP address.<br>
<br>
What I'm looking for is a way to tag the created port "lxdora7a" within the config file so that I dont' have to start the containers with these scripts.<br>

How do I put a VLAN TAG=10 on the above so that the lxdora7a port on my sw1 switch gets created with a TAG=10?<br>

<p><code><span style="font-family:arial,sans-serif"><span style="color:rgb(0,0,0)"><font size="3">I could not find a reference for how to add VLAN tagging in the lxc config file above, but I was able to manually put the VLAN tag on the port that the LXD container
automatically creates when it boots using the following command after it had already booted. At that point, eth0 is still unconfigured even though onboot is set to YES in the ifcfg-eth0 because the VLAN 10 is not passing the traffic from the LXD container
lxdora7a because of the VLAN'g.</font></span></span></code></p>
