Hi Michael, That [1] file is generated by this udev rule: -- /usr/lib/udev/rules.d/75-persistent-net-generator.rules -- Not trivial to follow, but you can see how some interfaces are skipped.
For many VM guests, no [1] file is auto-generated. None of my KVM Hypervisor Guest VMs have a [1] file. Though in all cases the first interface is "eth0". I have never needed it, but you could add a manual [1] file (with specific MAC addresses) if needed.
