From c01962bf88786dd84ad83cc1d315297607d29f7c Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Tue, 6 Sep 2016 14:46:10 +0100 Subject: runqemu: Allow unique network interface MAC addresses Current qemu instances all share the same MAC address. This shouldn't be an issue as they are all on separate network interfaces, however on the slight chance this is causing problems, its easy enough to ensure we use unique MAC addresses based on the IP numbers we assign.
