“I’ve found an even easier way to do this.  I found a PowerShell Hyper-V script at:

It has a lot of functions already, and I added a “Kill-VM” function that automates the kill process:

My modified script is attached to this message.

To use it, you need to install PowerShell (Under Server Manager -> Features in Win2008).  Once installed, run PowerShell from Start -> Search, find the script, and type:

FreeBSD on Hyper-V – shutdown hangs…

shutdown -p now

and when it turns off I turn it back on with Hyper-V console…

ifconfig de0 – this is IP in my subnet you should use one of your free IP’s
ifconfig de0 down
ifconfig de0 up

You can now chec status of your IP with:

Ok, now we need a gateway to get to the internet:
route add This will add your default gateway (for example my gateway is…

try to ping an public IP address to see it is working… As you can see in my screenshots it works for me. 🙂
