My host runs LXC 4.0.6 on Debian 11.6, IPv4 only environment.
I have a bunch of Deb 10 and 11 containers all suffering from a delayed startup:
[ *** ] A start job is running for Raise network interfaces ( x / 5 min)
When in /etc/network/interfaces on each container I change “auto eth0” to “allow-hotplug eth0” the boot message changes to:
[ *** ] A start job is running for /sys/sub...devices/eth0 ( x / 1min 30sec)
but then no IP is assigned to the container and network connectivity doesn’t work.
Any idea how to remove the delay entirely?
