When changing an arch or ubuntu 18.04 containers to priviledged. It will either not start or loose network connection.
my network setup is:
lxc profile show lan-br0
config: {}
description: “”
devices:
eth0:
name: eth0
nictype: bridged
parent: br0
type: nic
root:
path: /
pool: lxd
type: disk

used_by:
- /1.0/instances/u-18
- /1.0/instances/arch1
- /1.0/instances/arch2

But when creating the container as privileged (unlike changing existing to privileged)
the ubuntu container is running with network. The archlinux container runs, but fails to create a network connection (ipv4 network). It does create an ipv6 network)
