On my vSphere client, and go to Host->Configuration Tab->Network Adapters, I get the following:

   Broadcom Corporation BroadcomN NetXtreme 1 GB ....
      vmnic1   Down         Negotiate   None       
      vmnic0   1000 Full    Negotiate   vSwitch0   

Open in new window

I do not see my 10GB card

Then I go to Host->Configuration Tab->Advanced Settings, and I see the following

  Direct Path I/O Configuration

  Warning:  Configuration host hardware without virtualization features for virutal machine
  passthrough will make it unavailable for use except for dedicating it to a single virtual
  machine.  In particular, configuraing a device needed for normal host boot or operation
  can make normal host boot impossible and may require significant effort to undo.  

  Broadcom NetXtreme 10GB

Open in new window

So what seems to be happening is that this NIC can not be assigned virtually to a VM

I have 2 questions

1> How do I assign a NIC directly to a VM (This NIC does not show up in Network Adpaters))

2> I have the exact same NIC (same part number) on the exact same machine and the same hypervisor, and the NIC works great on the other machine and can esily be assigned to a vSwitch.  Why would this be ?

    You are MISSING the drivers for your 10GB NIC!

    What is it?

    What model of server do you have?

    Direct Path I/O Configuration is not the answer here, it should be assigned to the Host Server, which if you use the correct driver it will show up.
