Can’t select Network Adapter in Hyper-V Manager

The most likely reason why you can’t select the network adapter in the Hyper-v Manager is due to the fact you most likely haven’t set up a virtual Network in the Virtual Network Manager.

Here’s the steps to setup a virtual network in Hyper-V.

Open the Hyper-V Manager and click on the the “Virtual Network Manager…” link in the far right Actions column.

Click “New Virtual Network – External – Add

Type a name into the Name field. If you only have one nic make sure that you select “Allow management OS to share this NIC”. Hit “OK”.

If you are prompted with any questions say yes. It’s going to disrupt the Virtual machine if it is running.

Go back to the properties of each virtual machine and make sure to select the network you just created and hit apply.

*NOTE* – Remember if you are installing a “dumb” OS where you can’t install MS Integration tools,  you will most likely have to remove the current NIC and create a legacy NIC instead.

Network Adapter doesn’t show up in Windows 2003 Hyper-V Virtual machine

The most likely reason why the network adapter doesn’t show up in a Windows 2003 virtual machine is that you need to use a legacy adapter. In order to use a legacy adapter you need to:

  1. Make sure that the virtual machine in question is turned off and is not in any hibernation state.
  2. Once that is done you right click the Virtual machine. Remove any NIC’s that may currently be installed.
  3. Click “Add hardware”. It should be the top most option.
  4. You will select Legacy NIC
  5. Apply the settings and start the virtual machine

Notice that the Legacy Network Adapter will be yellowie-orangish color and say “Legacy Network Adapter”.

How to copy files from Hyper-V host to clients

I’ve been doing a deep dive into hyper-V. While I think Microsoft has it’s leg up on VMWare with price and performance it’s still lacking in the tools arena. One thing I was wanting to do was transfer a file from the Hyper-V host to the Hyper-V client. The Hyper-V client machines were running in a different subnet then what my original machines were running in.

After doing some searching around I found a great article about setting up a private virtual NIC on both the Hyper-V Host and Hyper-V client and setting the IPs to the same subnet.

While this might be OK for some people I really miss the ability to just copy files from the host machine like I could in Virtual PC/VMware.

After day dreaming for a bit how this could be done I thought I remember seeing an option in Windows 7 Disk manager to not only CREATE but Mount VHD files. I then started thinking what if I create a VHD and then mount it. Copy the files to the VHD and then mount the VHD in the virtual machine.

It could be like using a networked USB Drive.

Open Disk Management in Windows 7. Create VHD.

I saved this file to my desktop. It doesn’t seem to let you save to a network location.

You will need to initialize the disk

This will walk you through the volume and format wizard. I am assuming you have experience with this.

Copy the files you want on the virtual disk drive.

You will need to “detach” the VHD drive in Drive Manager.

Click “OK” when this window pops up.

Copy this VHD to the Hyper-V Host. I like to put it in a shared directory I use for media. ie. iso’s & vhd’s etc.

Open the properties of the virtual machine.

Add a Hard drive. Point the wizard to where ever you copied the newly created VHD.

Hit apply.

Boot up the Virtual Machine.
