No I just eth0 was configured during OS installation. All other
interface have been configured through the oVirt GUI.

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

DEVICE=eth0
ONBOOT=yes

[root@lxedna ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1

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.
