Have you figured this one out? I am running into the same problem.

Code: # /etc/systemd/network/99-default.link [Link] MACAddressPolicy=none followed by a ` systemctl restart systemd-udevd` Udev sees a new network device and decides it wants to generate a persistent mac address for it, but these devices are temporary virtual devices which are about to be moved into the container's namespace, there's no point in doing anything with them really, especially since they're usually gone by the time it starts acting.

Edit: As for the IPv6 message. My general advice is to have net.ipv6.conf.default.disable_ivp6=1 and only enable it explicitly on interfaces where you want to use it (same for.autoconf and.accept_ra). The container will usually enable/disable it on its own side anyway. Click to expand.

Thanks for pointing out Wolfgang. It helps in understanding that my problem isn't related to this thread then. I'm having an extremely weird behavior while starting containers in the new PVE 5.1. Basically, it fails when executing the script /usr/share/lxc/lxcnetaddbr while starting the container. I noticed this because I generated a log while running the container in foreground mode.
