Windows Phone 8 emulator error - Something happened while creating a switch

Question

I have a similar problem like mentioned in this question:

Unable to create the virtual machine

But, my problem is a bit different in the error description:

Answer 1

It's already answered, but something easier worked for me (and without uninstalling VirtualBox):

"Go into Hyper V. Go into the Virtual Switch Manager. Create a virtual switch called 'Windows Phone Emulator Internal Switch'. Make it's connection type Internal. Now launch the emulator. It should work."

I had to reboot the machine before running the emulator, but now everything's working fine: VS2012, Xde and VirtualBox.
