You should write details of your setup so that others can help you better. On default setup (with lxdbr0), c8 container works just fine, so it's definitely not 'impossible to containerize'. # lxc launch images:centos/8 c8 Creating c8 Starting c8 # lxc shell c8 [root@c8 ~]# nmcli connection show NAME UUID TYPE DEVICE System eth0 5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03 ethernet eth0 I'm guessing you've changed it to use macvlan. It can work, but you need a workaround, using the old network-scripts, and lxdbr0 bridged mode temporarily (or whatever you need to be able to run "yum install" on the container) yum -y install network-scripts systemctl enable network sed -i 's/TYPE=Ethernet/TYPE=Generic/g' /etc/sysconfig/network-scripts/ifcfg-eth0 change container config to use macvlan, then reboot the container. The correct fix should probably be in network manager, so that it could work with existing macvlan device, or have the option to override detected device type. -- Fajar _______________________________________________ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
