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
6:15 a.m.
Christoph,
Are those nodes bare-metal or they're VMs?
Regards,
Yevgeny

Hi,
I'm using currently the following:
But the problem is not new.
ovirt-engine.noarch 3.6.6.2-1.el7.centos @ovirt-3.6
vdsm.noarch 4.17.28-1.el7 @centos-ovirt36

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

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 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.

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