How does the predictable naming conventions work in VMs? I see they always differ slightly. Are we not using a pool of expected syntax like 1/2/3 ??? Or is it built on things like mb.vendor, # nics, and other arbitrary things like that? I've been reconfiguring servers that were vMotioned from one

Here's the description of the naming convention that is used, taken from the kernel source:  Two character prefixes based on the type of interface:    en — Ethernet    ib — InfiniBand    sl — serial line IP (slip)    wl — wlan    ww — wwan Type of names: b             — BCMA bus core number c
