systemd-networkd in LXC Container Nesting enabled - PVE not coming up anymore ??

[liszca]

In my defense, I screwd up my apt cacher by removing some the crucial network packages.

As I couldn't install anything with apt I tried to get network back using systemd-networkd. That didn't work. After that I gave the node a reboot. It never came up again. Sadly I that peace of hardware got no RS232 port and an Monitor is not at hand today

This shouldn't be done in the first place?

Where are the limits with systemd and inside LXC?

Managed to get physically into the PVE and there is no network interface showing up when

ip a

is run, not even the loopback interface.

I assume - but don't know how to proof - the configuration in the lxc container with nesting feature enabled might have caused this.

the correct network configuration is found in

/etc/networks/interfaces

how can I check if I messed up udev config, where I switch to interface names to unique ones based mac-addresse?

An external USB Ethernet Adapter doesn't show up in any shape or form when running

ip link

Oldest kernel didn't change anything.
