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

Christoph,
Are those nodes bare-metal or they're VMs?
Regards,
Yevgeny

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.

through the oVirt GUI.
I mean by reordering that after every reboot some interfaces are not the

Perhaps Christoph refers to the problem that [1] was meant to solve?
[1] https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInter...
To add on what didi says, this should be the default with el7's systemd.
It is surprising that your nics are named eth*, and not by the
predictable nic name scheme.
Maybe if you share your `lspci -vvv` and /var/log/messages of two
different boots, we can have a hint regarding your instability.

Hi Dan,
I'm using the kernal parameter net.ifnames=0 to have the old naming schema.
I will try to get rid of it on the machine and check if this is solving
my issue.
Best regards
Christoph
