</div></div>That shows that your container is inheriting from the "default" profile<br>
which likely does include that eth0 device.<br>
<br>
lxc config show --expanded my-ubuntu<br>
<br>
Would show you the config with the profiles applied.<br>
<br>
To remove something that's inherited from a profile, you have to mask it<br>
with something like:<br>
<br>
lxc config device add my-ubuntu eth0 none<br>
<br>
Which masks the inherited device "eth0" with an empty one.<br>

<br>
</div></div>To attach it to a different bridge, you'll want to mask the inherited<br>
"eth0" with another eth0 that's attached to the bridge you want:<br>
<br>
<br>
lxc config device add my-ubuntu eth0 nic nictype=bridged parent=new-bridge<br>
<br>
<br>
Or on recent LXD, this will achieve the same:<br>
<br>
lxc network attach new-bridge my-ubuntu eth0<br>
