Hi all,
I added a new nic on all my vms, but the MAC address pool was too small.
So I extended it from 00:1a:4a:22:1f:00 to 00:1a:4a:22:1f:ff =>
00:1a:4a:22:1e:00 to 00:1a:4a:22:1f:ff.
It was okay but when rebooting some vms, nics are interverted and I
couldn't join my vm on ip!
I noticed nics were ordered now from the smallest MAC address to the
greatest one, so the last plugged nic from the new pool was now the
first in the vm, and all nics were moved at the bottom.
Is it an expected behaviour?

No. As far as I recall, and Yevgeny can add more details, reordering
of vNICs happens only when allocating multiple nics in the initial
definition of a VM; but not on plugging of a nic to an existing VM.
Which version of ovirt-engine do you use?

You can activate reordering by using oVirt REST API. Sending POST request
to http://${engine_address}/vms/${vm_id}/reordermacaddresses URL should do
the job.
Please note that it would reorder all vnics of the VM that PCI address
wasn't assigned to them, in other words the VM wasn't run since the vnic
was added to it.

Sorry, please ignore my suggestion. Now I realize that you actually want to
avoid re-ordering.
