Hi there
if you UPGRADE to W8.1 rather than clean install then the VMware adapter settings (ON THE HOST) get hosed up. Your VM's won't be able to connect to your network ( and / or the Internet too).
Either re-install the adapters manually - via the VMware program "Repair program" or uninstall VMware and install the latest version - in my case VMware workstation 10.0.1
I made another post about this in the Forum elsewhere.
I didn't encounter this issue when I upgraded my machine to 8.1 but I'm running VMWare Player. In addition, the first time I went to fire up Player, it prompted me to install a new version.
My VirtualBox VM's seem to be working fine after the upgrade.
