Instance details

When launching an instance (container or VM), you can immediately run incus list mynewcontainer to see what's going on. The output of the command shows that the instance has multiple IP addresses (plus 2 multicast), both IPv4 and IPv6. After a few seconds, the list clears up and the instance looks and works properly.

Example output for container (also happens with VM)

$ incus list mynewcontainer

Expected behavior

The incus list command should only show the appropriate IP addresses that the instance is supposed to use.

Steps to reproduce

  1. Launch an instance, incus launch images:debian/13/cloud mynewcontainer
  2. Run somewhat quickly, within a second, incus list mynewcontainer
  3. The output of the incus list command should show a bit list of IP addresses as shown above.
