I've got Windows 8 Pro on my home machine. I want to have a Windows 7 Professional VM running under Hyper-V, and I want the VM to have full internet access. My physical machine has a wireless network adapter I use to connect to a router.

Here's what I've done so far:

  • In Hyper-V Manager, I've created a new External Virtual Switch, which is connected to my wireless network adapter. If I look in Windows 8's Network Connections page, I can see it's created a virtual ethernet adapter and a network bridge, and my wireless adapter is now bridged.

  • I've created a Windows 7 VM, and in the Hyper-V settings I've set it to use the virtual switch.

When I log into the VM, I have a network, but it's "unidentified" and has no internet access. What am I missing? Is it something to do with the "VLAN identification" settings? I'm not quite sure what these are about.

In order to get the VM connected to the internet you have to tie it to the Ethernet/Wireless NIC Card. In order to do this you have to create a "Virtual Switch".

  1. Open your Hyper-V Manager
  2. Select Action --> Virtual Switch Manager

    Accessing the VM Switch Manager

  3. Select External and then Create Virtual Switch

    Virtual Switch Manager

  4. Give the Switch a Name and then select the External Controller you use to connect to the internet (Ethernet, or Wireless NIC, etc,.)

    VM Switch Properties

  5. Select Apply and then OK

  6. Right click on the Virtual Machine you want to connect and select Settings

    VM Settings

  7. Under the Network Adapter Setting select the newly created Virtual Switch

Connecting the Switch to the VM

This should enable the connection you use to connect to the internet to be accessible to the VM

This is a great description, but it's exactly what I did. I did manage to get it all working though, I'll check at home this evening and either add an answer or mark someone as correct. –  Graham Clark Sep 12 '12 at 10:44
    
Not exactly sure how I got it working, I think I'd ticked the "Enable virtual LAN identification" box and then unticked it whilst the VM was running - for some settings like this, the VM needs to be off/restarted to take effect. –  Graham Clark Sep 13 '12 at 19:37

This procedure installed a network bridge under "Control Panel\Network and Internet\Network Connections". Every time I boot the VM I have to disable then enable the bridge (via its right-click menu). I've read similar accounts from others. Hope they get it ironed out. –  JohnB Jan 9 at 2:37

I had to disable and then re-enable the Allow management operating system to share this network adapter under the Virtual Switch Manager.

If this isn't checked the host machine will not be able to use the chosen adapter. It had been checked in my case, for some reason I had to flip it back and forth again.

I had to disconnect & connect my wireless connection after disable & enable step. –  Joymon Apr 25 at 5:56

Another trick as detailed in this question Windows 8 Hyper-V network not working on host is that this may not work over wireless... re did the setting several times nothing - set up an ethernet adapter - worked straight away. [quick edit to say of course I'd set up separate virtual switches for the two physical adapters...]

In my case, while the VM was running I changed the virtual Switch settings to “Not Connected” and then back to my newly created virtual switch. Worked.

Without rebooting I managed to get it working with a wireless adapter, which otherwise was doing nothing.

Open the network connections control panel

You'll see the virtual adapter setting has created a network bridge.

enter image description here

Right click on your Wi-Fi adapter (the one with the signal strength icon) and select Connect/Disconnect

Then you have to click the On switch that comes up in the sidebar and select your network. For some reason it was Off even though I was online before.

enter image description here

Everything then magically lit up and I was able to access the internet from within my Win XP VM immediately.
