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 IP...

Hi, kickstarting fails due to problems with host resolution, even though the network seems to be properly configured through DHCP. eno1 and eno2 are both attached to the network, but only eno1 gets an IP via DHCP.

...forget that there could be other tools running on the host which fiddle with NetworkManager. That said, I usually don't use NetworkManager on my servers so I don't really know much about it.

> Dear Simon, > > >> And can you diff the config of eno1 and eno4. > > # pwd > /etc/sysconfig/network-scripts Okay, nothing to find here. What about eno2, you also have two IP addresses there and even in the same subnet, is this wanted or not? Can the second address of eno2 be found in the ifcfg file? Both eno2 and eno4 have "scope global secondary dynamic" with the second address and it doesn't seem to come from the base configuratio...

I should have what i want to achive. The server is intended as a host for VMs. Our network has multiple VLANs, and the VMs will be connected to different VLANS. The interface eno1 is for host traffic and eno2 is connected to the trunk port of the switch, making the different VLANS availabel to the VMs via the br0. I want to use a VLAN-aware br0, so that I specify in my VM config (on the host side) which VM connects to which VLAN. is it true that br0 and eno2 need to have the same mac? Someone sugges...
