Is there a way to target an interface without knowing its name or mac address?

We're running a handful of virtual servers at OVH, which use openstack.

Most of the servers have a public interface as well as a private interface which is connected to a "virtual private cloud", or vRack as OVH terms it.

I've seen a few times that a server goes away, and then comes back up with the private interface having a new name (e.g. ens6 instead of ens4) as well as a new mac address.

This breaks the netplan configuration, which usually looks like a variation of this :

network:
    version: 2
    ethernets:
        ens6:
            addresses: [192.168.100.71/24]
            dhcp4: false
            match:
                macaddress: fa:16:3e:bc:73:48

That shouldn't be happening. Did you report the problem to OVH? – Michael Hampton Aug 19 '20 at 14:23

s means PCI slot, so the (virtual) hardware changed. Complain to the hosting provider that you want predicable hardware. – John Mahowald Aug 19 '20 at 14:56
OK, so based on the feedback here this should not be expected from OVH in any case. I'll report this back to OVH if / when it happens again. – sbrattla Aug 20 '20 at 04:59
