Containers not getting ipv4

Hi!

When you create a managed network (as you did with lxc network created lxd0), you get a DHCP server from LXD (not a system DHCP server).
If you have some other DHCP server on your host, it may conflict with the one by LXD.

So, show us the output of

  1. lxc network list
  2. lxc network show lxd0
  3. sudo lsof -i :53 (on the host)
