After trolling google, kodi wiki/forums, vc wiki/forums, virtualbox wiki/forums trying two VMs, exporting, reimporting, reverting, new building a stock image with nothing but VC and its prereqs. Win8.1, restore win7, win10 tech preview. No UAC, no FW, run as admin.
Still nothing worked.
Remotes/webinterface/eventghost worked. Changed VM settings, NICs, ....etc. But not in VC.
Just before bed I realize i have a old kodi installation on my Mac, I update the plugin accordingly and poof....events are flying. Kodiv14.0 on Mac seems fine....but my main htpc is running Kodibuntu updated to Kodiv14.2 the latest release pre v15 and the stable versions for DL. Still dont get if its a kodi problem how all the other things work just not to VC.
