Hi, I don’t think he was asking what you addressed.

In response to what was asked, I think there is no difference if you use the ps cmdlets to create a like for like switch as you would in the GUI, i.e. smae Teaming mode and Load balancing mode.

I had not noticed that before, but yes, it does seem logical to me. VMQ is a hardware offload and MAC spoofing is a software intercept, so the queue would get confused on how to deliver frames.

When I enable MAC Address Spoofing in HyperV Manager (vNIC settings tab), VMQ is no more active on the Virtual Adapter. Is it expected behavior?

It’s not supported to mix multiple team adapters with a virtual switch. It can work, but the QoS and VLAN behavior gets really confused and behaves unpredictably. A team with a vSwitch should have only the default team adapter. Use vNICs for anything else.

The article contains multiple examples of using Get-VMNetWorkAdapter to select exactly the item that you want. Pipe its output to Rename-VMNetworkAdapter.

Thanks for the post, it’s very useful for me!

If I added more than one VM Network Adapter via GUI, all adapters are added with same name- “Network Adapter”. If I try to rename one of them, using Rename-VMNetworkAdapter -VMName “MyVM” -Name “Network Adapter” -NewName “Adapter1” then all adapters with name “Netwotk Adapter” are renamed to the newly typed name.

Is there any way to select exactly which adapter from a list of adapters with same name, I want to rename?
Thanks!

thanks.

I’m not certain that there is a solution. You certainly can’t spoof the MAC using the Hyper-V tools for an IOV NIC.
You could try setting the MAC inside the guest OS. The properties for the NIC might have a “Hardware Address” field. You might need to change the vNIC’s properties in the host to enable teaming.
