SR-IOV Broadcom NetXtreme-E Virtual Function for Hyper-V

[Steven Harris]

Hi Everyone,

I have a HPE Proliant DL380 Gen11 with a Broadcom NetXtreme E-Series Dual-port 25Gb SFP28 Ethernet OCP 3.0 Adapter (Broadcom driver 231.0.158.0)

On the Hyper-V Host

The Server is running Windows Server 2022 and has the Hyper-V Role Installed.
I have created a VSwitch and SR-IOV enabled
I have created a VM running Windows Server 2022 with a network adapter 'bound' to the SR-IOV vsiwtch, and enabled SR-IOV under 'Hardware Acceleration"

In the Virtual Machine
In device manager, two network adapters are shown:
Ethernet 2 Broadcom NetXtreme-E Virtual Function for Hyper-V Up     Broadcom Inc (231.0.158.0)
Ethernet   Microsoft Hyper-V Network Adapter                 Up     Microsoft

Issue:
The VMs Ethernet adapter is not using the "Broadcom NetXtreme-E Virtual Function for Hyper-V"

Nothing is returned when I enter the powershell command:
Get-NetAdapterSriovVf

On the Host:
Get-VMSwitch -Name "SR-IOV vswitch" | fl *iov*
IovEnabled               : True
IovSupport               : True
IovSupportReasons        :
IovQueuePairCount        : 69
IovQueuePairsInUse       : 20
IovVirtualFunctionCount  : 8
IovVirtualFunctionsInUse : 2

Get-VMSwitch -Name "SR-IOV vSwitch" | Select Name, IovEnabled
Name           IovEnabled
SR-IOV vSwitch       True

In Hyper-V, the network adapter connection is using SR-IOV vswitch, and the status is OK (SR-IOV active).

Any help in making the VMs Ethernet adapter use the "Broadcom NetXtreme-E Virtual Function for Hyper-V" instead of the 1Gb adapter would be greatly appreciated!

Thank you

Steve Harris

I noticed you posted the same question on both the Microsoft and HPE forums. Since this appears to be a Microsoft-related issue, I recommend opening a support ticket directly with Microsoft for more accurate assistance.
