Hi,
Do I understand it correctly that:
-your OS uses PCI addresses to order NICSs?
-PCI addresses of NICs are in fact non-consistent between VMs?
So you boot VM1 (with NICs vNIC1 and vNIC2) and VM2 (vNIC3 and vNIC4) with same
order in eg. API (->GUI) and you sometimes see different PCI addresses (vNIC2
has higher PCI address than vNIC1; however vNIC3 has higher PCI address than
vNIC4)? I am surprised about that…
BR,
Konstantin

Betreff: [ovirt-users] Re: NIC Ordering
I don't create the VMs directly in the UI but use the API with Foreman. If I
change the MACs on the NICs I have to go back and update Foreman as well.
My workaround today is unplug the NIC I want to be second, briefly power-up the
VM so the "first" NIC gets assigned a PCI address, shutdown and re-plug the
"second" NIC. On power-up the "second" NIC will be assigned a later PCI address
and so achieve the ordering I want.
It's just fiddly and can only be done on first boot. I was hoping for a more
elegant solution that works when you have large numbers of VMs to provision.

I think it depends on the mac addresses.
If you see that the MAC addresses are not sequential, delete the NICs and
recreate them in the order you want them to be

Is there any way to enforce NIC ordering so the vNICs match the ordering in the
Engine UI?
I found this but not clear if it was ever implemented?
