Network Interface order changed after reboot
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 On Thu, Jun 23, 2016 at 3:49 PM, <ovirt@timmi.org> wrote:

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.

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 Am 27.06.2016 um 08:29 schrieb Dan Kenigsberg:

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)

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.
