Hi Edy,<br>
<br>
please find some config files below. I did the interface config only
through the oVirt GUI.<br>
<br>
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.<br></div></blockquote><div><br></div><div>This sounds like the problem Didi referenced to.<br><br></div><div>Before you configured the interfaces through oVirt, wasn't there any ifcfg files?<br></div><div>(just to understand why you have not seen this before, without vdsm on the host)<br></div><div> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div bgcolor="#FFFFFF" text="#000000">

<br>
I have two nodes (running CentOS 7) and the network
interface order changed for some interfaces after every
reboot.<br>
<br>
The configurations are done through the oVirt GUI. So the
ifcfg-ethX scripts are configured automatically by VDSM.<br>
<br>
Is there any option to get this configured to be stable?<br>
<br>
Best regards and thank you<br>
<br>
Christoph<br>

<div class="gmail_extra">Hi Christoph,<br>
<br>
</div>
<div class="gmail_extra">VDSM indeed edits and takes ownership
of the interfaces for the networks it manages.<br>
</div>
<div class="gmail_extra">However, editing the ifcfg files should
not change anything in the order of the devices, unless it was
originally set <br>
in an unsupported fashion. An ifcfg file is bound to a
specific device name and I'm not familiar to device names<br>
</div>
<div class="gmail_extra">floating around randomly.<br>
</div>
<div class="gmail_extra">Perhaps you should elaborate more on
what it means by 'order changed'.<br>
</div>
<div class="gmail_extra"><br>
Here is an example of a setup we do not support (pre adding
the host to Engine): <br>
The initial ifcfg file name: ifcfg-eth0<br>
</div>
<div class="gmail_extra">The initial ifcfg file content:
DEVICE="eth1"<br>
</div>
<div class="gmail_extra">In this configuration, the name of the
ifcfg file is inconsistent with the name of the device it
represents.<br>
</div>
<div class="gmail_extra">VDSM expects them to me in sync.<br>
<br>
</div>
<div class="gmail_extra">Please provide the ifcfg files before
and after you add the host to Engine.<br>
