Hi Edy,
please find some config files below. I did the interface config only through the oVirt GUI.
I mean by reordering that after every reboot some interfaces are not the same as before. That means I need to change the cables after reboot.
This sounds like the problem Didi referenced to.
Before you configured the interfaces through oVirt, wasn't there any ifcfg files? (just to understand why you have not seen this before, without vdsm on the host)
[root@lxedna ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 # Generated by VDSM version 4.17.28-1.el7 DEVICE=eth0 ONBOOT=yes BOOTPROTO=dhcp MTU=1500 DEFROUTE=yes NM_CONTROLLED=no IPV6INIT=no [root@lxedna ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1 # Generated by VDSM version 4.17.23-0.el7.centos DEVICE=eth1 BRIDGE=Test-LAN-SW1 ONBOOT=yes MTU=1500 NM_CONTROLLED=no IPV6INIT=no [root@lxedna ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth2 # Generated by VDSM version 4.17.23-0.el7.centos DEVICE=eth2 BRIDGE=PC-LAN ONBOOT=yes MTU=1500 NM_CONTROLLED=no IPV6INIT=no

Hi List,
I have two nodes (running CentOS 7) and the network interface order changed for some interfaces after every reboot.
The configurations are done through the oVirt GUI. So the ifcfg-ethX scripts are configured automatically by VDSM.
Is there any option to get this configured to be stable?
Best regards and thank you
Christoph

Hi Christoph,
VDSM indeed edits and takes ownership of the interfaces for the networks it manages. However, editing the ifcfg files should not change anything in the order of the devices, unless it was originally set in an unsupported fashion. An ifcfg file is bound to a specific device name and I'm not familiar to device names floating around randomly. Perhaps you should elaborate more on what it means by 'order changed'.
Here is an example of a setup we do not support (pre adding the host to Engine): The initial ifcfg file name: ifcfg-eth0 The initial ifcfg file content: DEVICE="eth1" In this configuration, the name of the ifcfg file is inconsistent with the name of the device it represents. VDSM expects them to me in sync.
Please provide the ifcfg files before and after you add the host to Engine.
Thanks, Edy.
