SR-IOV VF Drivers for Broadcom NetXtreme E-Series Dual-port 25Gb SFP28 Eth OCP 3.0 Adapter
Hi All,
I am running Windows Server 2022 on the Host Proliant DL380 Gen11 and 2 x Virtual Machines
I have configured SR-IOV as per the steps below.
However, when I run in each VM
Get-NetadapterSriovVf
Nothing is returned (I think it should return 'true")
Step 1
SR-IOV enabled in the BIOS (including under the Broadcom NetXtreme E-Series, device configuration menu)
Step 2
On the Host, using powershell, I created the SR-IOV enabled external vswitch and set the ioweights:
New-VMSwitch -Name "SR-IOV Virtual Switch" -NetAdapterName "PCIe Slot 15 2 Port 1" -EnableIov $true
Set-VMNetworkAdapter DC-1 -ioweight 1
Set-VMNetworkAdapter FP-1 -ioweight 1
The last two commands 'injected' the Broadcom VF in each VM
Step 3 Good:
Get-VMNetworkAdapter -VMName fp-1 | fl Name, IovWeight, IovQueuePairsRequested, IovQueuePairsAssigned, IovUsage
Name : Network Adapter
IovWeight : 1
IovQueuePairsRequested : 1
IovQueuePairsAssigned : 1
IovUsage : 1
Step 4: Good
On the Host, I note:
Get-VMSwitch -Name "SR-IOV Virtual Switch" | fl
IovQueuePairCount : 69
IovQueuePairsInUse : 14
IovVirtualFunctionCount : 8
IovVirtualFunctionsInUse : 2
Step 5: Each VM I note an additional NIC:
Broadcom NetXtreme-E Virtual Function for Hyper-v
Manufacturer: Broadcom Corporation
Location: Virtual PCI Bus Slot 2 Serial 1
Driver provider: Microsoft
Driver date: 3/9/2020
Driver version: 216.0.143.6
Digital Signer: Microsoft Windows
Step 6: However, the Host is using:
Broadcom Inc
30/08/2024
231.0.158.0
Step 7: On the host, I note SwitchName is empty!
Get-NetAdapterSriov
Name : PCIe Slot 15 2 Port 1
InterfaceDescription : Broadcom NetXtreme E-Series Dual-port 25Gb SFP28 Ethernet OCP 3.0 Adapter
Enabled : True
SriovSupport : Supported
SwitchName :
NumVFs : 8
Step 7: Hyper-V Manager reports status:
OK, (SR-IOV active)
Requests:
Where do I find the broadcom VF drivers for the VMs to update to 231.0.158.0?
Have I missed any steps?!
Thanks!
Steve

Hi @DoJu
Please check if the host and VM adapters are configured with the name. If not showing, the command Rename-NetAdapter may help you in this.
Please refer to this document for more detail on Get-NetAdapterSriovVf
