This is happening with the Centos7-armv7 image 1804, but I was wondering if it is a broader C7 issue.
My image has only 2 ifcfg files: ifcfg-l0 and -link. 'ip a' is listing the ethernet as eth0. ifcfg-link has contains:
DEVICE=link BOOTPROTO=dhcp ONBOOT=on
I then used nmcli to create my ifcfg-eth0
nmcli con delete eth0 nmcli con add type ethernet con-name eth0 ifname eth0 ip4 192.168.129.11/25 gw4 192.168.129.1 nmcli con mod eth0 ipv4.dns "50.253.254.2 192.168.129.1" nmcli con mod eth0 mac "02:67:15:00:81:0B"
I moved the cable to the 192.168.129.1 vlan (which does not have a dhcp server), and
nmcli con up eth0 Error: Connection activation failed: No suitable device found for this connection.
Oops. ?
rebooting did not help. Came up with no address for interface eth0, yet no suitable device.
Where would I look to find what may be happening here?
I appreciate that this may be specific to armv7 and my Cubieboard2, but then again, it may be something known by other Centos people.
Thanks for any help!
