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.
[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

[root@lxedna ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth2

DEVICE=eth2
BRIDGE=PC-LAN
ONBOOT=yes

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.
