From c9a4779135c9f08ea678961256951896e7ac5c80 Mon Sep 17 00:00:00 2001 From: David Hunt Date: Wed, 11 Oct 2017 17:18:55 +0100 Subject: [PATCH 1/1] examples/vm_power_mgr: set MAC address of VF We need to set vf mac from the host, so that they will be in sync on the guest and the host. Otherwise, we'll have a random mac on the guest, and a 00:00:00:00:00:00 mac on the host.
