Hi,
I am a beginner with LXD. I followed these steps:
Then I created a 24.04 vm. It runs OK, but has no network connectivity.
On my host:

For some reason the enp5s0 does not have an IPv4 address.
I have been struggling with this for a few hours. Is there a description of the yaml format?
Thanks in advance for any help.
