So I just added a new NVMe card to my motherboard. Previously there was none - just a blank slot.
Booted the box up again and it wouldn't start the interface. Eventually found the interface name had changed from enp6s0 to enp7s0
Why would that be?
My guess is that effectively the network card shifted PCIe ports (from 6 to 7) - is that correct? And I'd then assume that's from adding a new PCIe device in the NVMe.
Its an Ubuntu Server 18.04.2 running KVM so that interface is mapped to a bridge interface (br0...and its this that didnt start cause it was pointing to a now non-existent interface).
Not a biggie as Ive sorted the mapping. Just curious.
