 I use VMWare Fusion on my Mac to run Windows on occasion, and hate having the extra 'vmnet1' and 'vmnet8' interfaces active even when I'm not running VMWare.  It causes all sorts of weird problems with Bonjour when the wrong interfaces start responding to requests.  In addition, VMWare uses the 172.16.0.0/16 network for their private interfaces -- which also happens to be the main network at my office.  This is a bad thing.

I don't need the NAT and Host-Only interfaces, because I use bridged networking. If you are using NAT or Host-Only, you need these interfaces -- although I do recommend switching to bridged networking, if only so your Windows instances will show up on the same network as your Mac and you don't have to deal with port forwarding. Of course, having Windows on the same network as your Mac could be dangerous -- so unless you understand the security risks involved with Windows... you should probably stick with NAT.   more...
