Trying to get this working on my Windows 8 Pro machine. I created an External Switch

Assigned the newly available adapter to a Guest machine with Win 2008 os. My host has internet connection. Host can ping Guest, Guest cannot ping Host.

Guest has no internet connection. Pasting the IP of both host and guest.

I had issues similar to this. It seemed to be caused by having other virtualization software (Virtualbox) installed along with Hyper-V. You could check the properties -> sharing tab of the vEthernet adapter and try setting it to share internet. I still had intermittent internet issues with this setup though.

I ended up uninstalling Virtualbox to get Hyper-V working solid.

Dont forget to activate the Virtual LAN ID which you can find in the Guest settings of the Hyper-V-Manager! http://i.stack.imgur.com/jrnm5.png

Unfortunately that seems to be the case:

System requirements / Specifications

An x64-based processor running an x64 version of Windows Server 2008 Standard, Windows Server 2008 Enterprise or Windows Server 2008 Datacenter.

Hyper-V System Requirements and Specifications

Credits to Diago:

The alternative to Hyper-V for Windows 7 is Virtual PC for Windows 7 available here. It is currently in RC but will be available soon. It also requires hardware assisted virtualization to work.

If you want 64-Bit VM's however you will have to load Windows Server 2008 and load Hyper-V since Virtual PC does not support this.

For 64-Bit VirtualBox or VMware are good options.

Windows 7 runs fine on Hyper-V, Hyper-V does not run on Windows 7.

As other people have said, you can use Microsoft Virtual PC or Vmware Workstation along with a whole load of other VM software.

Nick Whaley

You are stuck with Windows Server 2008 if you have to use Hyper-V. You can always switch to another virtualization software like VMware or VirtualPC or you can wait until Server 2008 R2 is released, which is the server version of Windows 7.
