Vista - IP assignment

Maybe I'm missing something here but I can only find passing comments
on this with no good descriptions.

I have a 2008 Std install with Hyper-V role. The server has 4
physical NIC ports.
I have one NIC devoted to the server
The first virtual machine (2008) is using the second NIC
The second virtual machine (2003) is using the other 2 NIC ports (the
app requires 2)

In Virtual Network Manager I have created 3 External virtual networks
and then added the adapters to the VM settings (1 for each port).

Everything is communicating fine but it looks like I am required to
supply an IP address to the physical NIC on the host system as well as
the virtual NIC in the VM. We can afford the IPs but it adds to
confusion and makes the host multihomed - this has several issues in
the MS world. It's also a little unclear how the apps will respond to
this method.

It looks like I could add the NIC in the VM as a legacy adapter to
solve this but that is documented as slower performance as well as
locking you to 100MB.

Am I understanding all of this correctly?

All you need to do is unbind TCP on the host with the NICs that are
dedicated to the VM's. That way the host wont need an IP address for
those NICs and wont use them for any of it's own communications.

Also,
That really wouldn't make any difference in this case. (And the
legacy NIC isn't locked to 100Mb, even though that's what it says, it
goes at the real NIC's speed.) The Legacy NIC is quite a bit slower
than the other type though, lots more overhead.

It shouldn't. You have to unbind it from the proper connection
(there's 2 for every NIC if I remember correctly) I don't have a
HyperV server here at work to check though...

Maybe someone else will chime it??

I agree with Bob on both points.

Regarding the network setup, you do not need any settings on the host
side for a vm to use the NIC. All you need is the virtual switch network
protocol. See this article from Ben's blog.

Whether you use a synthetic or legacy NIC in the vm cannot possibly
affect how this works. You must have something else configured incorrectly
(or there is a problem with the NIC driver software on the host OS).
