Hi John,

This may not be helpful but I can confirm that you should be getting
consistent naming.
Normally I actually get something like eno16777984  But I have a couple
systems that get named in the way that you mention.  When this happens I
normally see ens160 as the first nic and 192 if a second is defined.
I haven't dug too deeply into this but I would suggest that you look at the
udev rules that are defined in /etc/udev/rules.d/ and see if this explains
what is happening.   You may also want to check that the VMware Hardware
version is what you expect.
