Finaly we have a true solution for FreeBSD hanging when you want to reboot or stop it in Hyper-V server…
Today I recieved a comment on my article FreeBSD in Hyper-V – WORKS!!!. You can now patch FreeBSD kernel to shut down correctly…
Check this blog too: http://shell.peach.ne.jp/aoyama/
I made an easy patch for the kernel.
As a result, a virtual machine comes never to stop.
I expect someone to make the patch by a smarter method.
My patch can be downloaded from the following blogs.
This patched kernel confirmed the operation with
Server 2008 Enterprise w/Hyper-V and Hyper-V Server.
Thanks to Mike …
“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:
Kill-VM <VM name>
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:
Once loaded into memory, type:
Kill-VM <VM Name>

I am so happy – I managed to make it work…
What we need to make FreeBSD run on Hyper-V:
– download FreeBSD ISO image from:
Download this ISO image:
– create new Virtual Machine using Hyper-V
– remove default network card that is added by wizard
– add hardware and chose Legacy network adapter
– start the machine and “mount” ISO image to start booting FreeBSD…
– install it with parameters you want…
– **** NETWORK PROBLEMS **** Even if you are runing DHCP server on your network your FreeBSD machine will not get IP from your DHCP server (my machine did not) so I used ifconfig to add IP and gateway this way:
ifconfig de0 10.70.60.201 – 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 0.0.0.0 10.70.60.1 This will add your default gateway (for example my gateway is 10.70.60.1)…
try to ping an public IP address to see it is working… As you can see in my screenshots it works for me. 🙂

*** There is still one problem unsolved for now… If you try to reboot Free BSD, Hyper-V does not Turn off the machine … I am trying to solve that with some Nejc tricks 🙂
