# Basic Hyper-V Network Configuration

Hello, i am looking for support with Basic Hyper-V network configuration. I have reviewed many articles, and am still not quite able to get my basic configuration to work.

I am using a Dell R510 with Windows 2008 R2 SP1 as the host, and have only 1 virtual server configured currently. The virtual server name is Sharepoint2010. I have installed Hyper-V and SCVMM R2 SP1 on the host server. I installed SCVMM because i needed to perform a physical to virtual migration for Sharepoint2010. Sharepoint was previously installed physically, on an R710 with a similar hardware build. It was a painless migration.

Currently, on the host server i have 4 network adapters. However, only one is plugged in - Local Area Connection 2; which is a Broadcom BCM5716C and is configured with a dynamic address. I have attached screenshots of the network connections, and the properties of this adapter.

Currently, i have no network connections available from my Sharepoint2010 VM. When sharepoint was running physically, it had a static IP address. How do i get this working again? Thanks!

No, this is not related to the MAC address of the imported machine. A new MAC address is assigned from the pool of the Virtaul Network Manager.

It seems to me, you have missconfigured some of the virtual adapters. If it's not too late, I suggest you to stop the virtual machines, remove all virtual network cards from them and remove all virtual networks (virtual switches) from the Virtual Network Manager and start over. But before starting over, please read carrefully the following document Understanding Networking with Hyper-V from http://www.microsoft.com/download/en/details.aspx?id=9843. It explains very well the different types of virtual networks and how to configure them.

Ok, so i think i've resolved the issue, but now i'm just looking for an education really. I connected a 2nd NIC from the host to my network. The way i understand it is the NIC1 is for my host, and NIC2 is for connecting the Virtual Machines to my network.

I was able to configure my static IP for the Sharepoint2010 VM. However, i did receive a message about another adapter having the same network configuration. I don't see that configured anywhere, as all other adapters on the Sharepoint2010 VM and the Hyper-V host itself, are set to dynamic. The original physical machine where Sharepoint was installed previously is offline and in the process of being reloaded.

Alright so, do you have everything worked out?

Pretty much, i'm just concerned about the duplicate NIC configuration issue i mentioned in my previous post. Is that just a VM issue, or is it something i have configured incorrectly somewhere? I can not find a duplicate NIC config anywhere.

That is not a VM issue instead is a configuration issue possibly. Have you rebooted? Are you still getting this error after reboot? Post the whole error please

After restarting, i am unable to connect to the internet from my Sharepoint2010 VM. I've attached multiple screenshots. Thanks!

I just noticed, my default gateway was removed from my NIC config. It was there prior to restart.

I am still getting the same NIC config message though.

You have other Local Area connections.

Please post ipconfig /all from VM and Host server

In VM disable all network cards except for the one with the TCP\IP information see if you get the error after this.

If you still get error remove all network cards from  VM then add only one.

Reset the TCP\IP stack. http://support.microsoft.com/kb/299357

Same result. Odd.

There is another network card with a IP address on it. Remove all network cards this is why you are loosing you default gateway

Is this in any way related to the Mac Address of the NIC? Remember, i performed a P2V migration of sharepoint. Is that VM holding on the Mac Address of the Physical machine? I have reloaded this physical machine, and am in the process of applying windows updates, etc.

No the MAC should be generated from the VM settings but you can check

One more  thing go through this link it could help remove hidden network cards which might be causing the problem.
