Easy setup Let Win8 virtual machine under Win8 connect to the Internet

I believe that many friends have started using the pre-installed free virtual machine software Hyper-V under Win8. Still don't know if this is what? See Win8's earlier release of "Hyper-V Virtual Machine in Windows 8".
Under Virtualbox and VMware, Hyper-V uses a different network architecture. Click the Hyper-V Virtual Machine Manager, virtual switch management on the right side of the main interface to create a network connection.
In Hyper-V, there are mainly three kinds of network forms
External network (allowing virtual machines to communicate with external networks)
Internal network (allowing multiple virtual machines to communicate internally, between multiple networks, also Can be isolated by Vlan)
Pirvate network (isolated native network)
So, how can the virtual machine inside connect to the external network?

If you enable a virtual machine and have it connected to the Internet, you must choose the first: External network.
At this time, careful friends will find that in the Win8 host, the NIC structure itself has also changed. The IP address originally configured in the local connection has become the newly created connection (on the way to the network 3 local ), and the local physical NIC has become a virtual switch.

Finally, if you are using a router, automatically assign an IP address, go to the virtual machine and see if it has already been obtained. Can you go to the Internet?
