Hi all,

It was okay but when rebooting some vms, nics are interverted and I could=

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?

oVirt Engine Version: 4.1.2.2-1.el7.centos
