Hi all, Some time ago, udev changed to stable interface names for networking. So instead of eth0 and eth1 you would get enp0s3 (wired) and wlp1s5 (wireless) for example. And I think there existed a (nixos?) option to stick to the previous behaviour for some time.
I recently upgraded an older system to our new 14.04 release and noticed it now uses the new naming scheme, while it previously still used the old scheme. I could not find the use-old-scheme option, nor did I enable such a thing in the past. I do not mind the new names (actually, I prefer them), so I changed all references to the new names (firewall rules, custom networking setup, vpn tweaking). This works fine on the real system, but I run into issues when running such configuations in a vm. It seems qemu/kvm still has the guest create eth0. Now, I can of course parameterise the entire config by an interface name to easily modify the configuration for a vm build. But this is somewhat ugly, especially because of the networking.interfaces.<name>. attrset. But I'm hoping there's a better/nicer way to either force some interface name to vms, or have the real system stick to the old naming scheme. Any pointers?
