I installed Windows Server 2016 Datacenter on a Dell T620, and then I installed the Hyper-V Role. Next, I created a NIC Team comprised of 2 physical 1Gbps network adapters. Team is called LANTeam. Settings are: Teaming Mode - Switch Independent, Load Balancing Mode - Dynamic, Standby Adapter - None (all adapters active)
In this server's Network Connections control panel, I see all of my physical NICs, and I also now see one more connection called 'LANTeam'. That is the name of the connection but the Device Name is 'Microsoft Network Adapter Multiplexor Driver'
If I double-click on this network connection, it shows a speed of 2.0 Gbps which makes sense since this is 2 x 1 Gbps connections, teamed together.
Here's where things get a little cloudy for me:
I open Hyper-V Manager and click on Virtual Switch Manager. I create a new Virtual Switch (External) and select 'Microsoft Network Adapter Multiplexor Driver' from the drop-down list.
I name this switch 'LAN vSwitch'
Next, I create my first VM. In its Properties window I select 'LAN vSwitch' from the drop-down.
When I start this VM (I installed Windows 2016 Server), go to Network Connections and double-click on the one (and only) Network Adapter (which is just called 'Ethernet', it shows the speed is only 1.0Gbps.
Why not 2.0Gbps? My goal is to create a few VMs, all having a 2.0Gbps Ethernet connection.
