Dear Simon, every second IP-address is unwanted. We restarted? eno4: nmcli con down eno4; nmcli con up eno4 and the second address vanishes. Then after a few ours, the second ip address reappears. This is the config-file of eno2: # cat ifcfg-eno2 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=eno2 UUID=cb6fcb54-be52-4ab6-8324-88091a0ea1a0 DEVICE=eno2 ONBOOT=yes IPV6_PRIVACY=no IPADDR=10.10.100.205 PREFIX=24 GATEWAY=10.10.100...

Hi! I just upgraded a machine to 7.7.1908 and the default route is not being set on boot. This particular server has a bonded interface, and the corresponding configuration for the master is ( /etc/sysconfig/network-scripts/ifcfg-bond0): TYPE=Bond BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes NAME=bond0 DEVICE=bond0 ONBOOT=yes IPADDR=10.3.20.131 PREFIX=24

Dear CentOS-Community, we are facing the following issue: A secondary ip address seems to be automatically added to a nic which causes several issues in our setup. This server is equipped with four nics which are currently in use: # nmcli con show NAME????? UUID????????????????????????????????? TYPE????? DEVICE eno2????? cb6fcb54-be52-4ab6-8324-88091a0ea1a0? ethernet? eno2 eno4?????

Hi, Tonight I upgraded two CentOS 8 boxes to CentOS 8.1 (1911). Then after a reboot of the first server the network was unavailable. In IPMI console everything except the network was looking good. Network was unreachable. No errors in NetworkManager. I also restarted NetworkManager, but it did not help. Then I discovered that the default gateway suddenly was missing. Then I rebooted the

The proposed API is the same as v1, but this includes an implementation (for /etc/sysconfig/network-scripts/ifcfg-*) and modifications to virt-inspector. This compiles and works. If you look in patch 5 you can see proposed output as virt-inspector XML for a guest (although this guest has not been booted, so a real guest would hopefully have a hwaddr="MAC" attribute too). Rich.
