I have just noticed that I had sent this only to Andrew, not to the core-talk list.

The problematic interface is "virbr0" which may have something to do with VmWare being installed on the system. or maybe docker?

That's the NAT interface for virtual machines. Gets created by libvirt, VMware player, VirtualBox, …

My RHEL-7 machine also has a virbr0 interface (with exactly the same IP address) because I’m running VMs (but there are no IOCs running there, in case that makes a difference) and it passes these tests. Here is my output from the new version for comparison.
