Hyper-V server 2008 R2 network "VLAN" help!

I have 1 SAN device with 2 host servers runing Server 2008 R2 CORE with Hyper-V server.
I have the virtual servers configured, and running successfully off the SAN, however I cannot get networking to work with the virtual land and the virtual servers.

In hyper V on a full edition of windows server with a GUI, I have it working properly, by assigning a gateway to the virtual switch adapter, and the setting the IP information on the virtual box itself.

When I add a VLAN with an unused adapter, the Hyper V server reports that the network switch adapter replaces the physical device in the network connections list.  And assigns it an IP address of 169.x.x.x.  I have attempted to configure this as well. (IP/SUB/GW)

I must be missing something!

This issue remains.

Additionally I attempted to setup static IP addresses, and DHCP addresses on different adapters, create a new VLAN with the hyper v console, and it always displays on the host server as a 169.x.x.x address after it creates the virtual switch.

Yes,
I tried several different numbers.  But it does not appear that any traffic is going through, so I am not sure how the tags help?

Heh, mate, you don't have to "try different numbers". What is your goal? Place nic of your virtual machines in different vlans? If so you have to:

1. Configure VLAN trunking on your physical switch.
2. Configure VLANs TAG and ID on your Hyper-V server Nics
3. Create and attach interfaces to Hyper-V virtual switches, don't forget to assign vlan tagging there.
4. Enter virtual machine configuration, attach virtual nic to virtual switch, assign vlan tag id there.

Jack,
That is what I have done to this point.  Unfortunatly, it is not working!  I have no connectivty between the virtual network and the actual network.

One of the things I've found to be problematic, is having the "Enable virtual network optimizations" box checked. If you're having issues with connectivity, try unchecking that box.

Also check to ensure that your virtual network adapter is connected to the correct interface.

I found that the issue was the VLAN ID was not working with my adapters.  Disabling the ID on the VLANS, and they started working.
