I've added a VM in Hyper-V on Windows 8 Pro and created a Virtual Switch. The Virtual Switch is set to "Internal network".

On the host machine, I go to Control Panel > Network and Sharing Center > Adapter Settings and bridge the newly created "vEthernet" adapter and my existing (and working perfectly) Wi-Fi connection. Once Windows has finished configuring the bridge I lose connectivity on my host machine. What am I doing worng? What is the correct way to configure a network so that the VMs can get to the outside world?

I'm running RTM Windows 8 Pro (v6.2 build 9200).

Creating an External network has exactly the same effect of killing my physical connection.

Stop trying to bridge the Virtual Switch adapter with ANY of the physical network adapters in the host. That's not how Hyper-V networking works and is no doubt the cause of your problems. The correct way to implement networking in Hyper-V for VM communication that needs to occur between the virtual machines and the rest of the external network (the network beyond the Virtual Switch) is to create an external Virtual Switch on one of the physical adapters on the host, preferably a NIC dedicated for Virtual Machine communication. If you only have a single NIC in the host then that can be used for both host communication and for VM communication, although it can't be a wireless NIC.

Then I guess it's the fact I'm trying to use my WiFi. –  Greg B Nov 7 '12 at 16:16

Internal network can only talk to each other and to the host. You can't connect such a vswitch to an Ethernet adapter. The correct option is to use an "external" vswitch type.
