Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
After upgraded lxc from 4.0.6-2 to 4.0.10-1. lxc container cannot start.
I find the error with "lxc-start -l trace" like below:
network.c:lxc_network_setup_in_child_namespaces_common:3894 - Cannot add ipv4
gateway for network device "eth0" when not bringing up the interface
network.c:lxc_setup_network_in_child_namespaces:4038 - Function not
implemented - Failed to setup netdev
conf.c:lxc_setup:4080 - Failed to setup network
start.c:do_start:1291 - Failed to setup container "vbox"
If I rollback to 4.0.6-2, everything work fine as before.
If I remove the line "lxc.net.0.ipv4.gateway = 10.0.3.1" in
"/var/lib/lxc/vbox/config" (container config),
the container can start again, but result no network , only loopback
interface (lo) in container (no eth0 in container).
Thanks.
