Genymotion issue with Windows 10 10586

I use Genymotion for my Xamarin Android development, I know that both Xamarin and Microsoft provide their own emulator but, for my machine configuration Genymotion is the one I like most at the moment.

This post is to help you find a solution in case the virtual device doesn’t boot on a machine after the upgrade to TH2 aka build 10586, with this message:

obviously the message is meaningless, digging into device log file located at %LocalAppData%\Genymobile\Genymotion\deployed\ I’ve discovered that error depends on a network issue:

0:00:01.362237 VMSetError: Failed to open/create the internal network ‘HostInterfaceNetworking-VirtualBox Host-Only Ethernet Adapter #4’

After doing several test and internet search I finally found the reason of the problem: no idea why but an option in the adapter settings was not selected:

The option is: VirtualBox NDIS6 Bridged Networking adapter, if not selected, select it and try again, your emulator should now work (or at least, it worked for me)

Hope it works for you too, otherwise good luck finding the solution, if you find it please share, Genymotion support for free licenses is far than optimal.
