Question
We have a SYS-122C-TN that came with Mellanox ConnectX-CX7 network card.  After we installed the Windows 2025 and run the powershell command "Get-NetAdapterSriov" to check on the SRIOV support, it returns SriovSupport: NoIoMmuSopprt
How do we enable IoMmuSupport on the Mellanox ConnectX-CX7 SRIOV?

Answer
For windows, the sriov only enabled if you install HyperV to host VMs which is SRIOV use for.  To install HyperV, see command below.
Powershell:  Install-WindowsFeature -Name Hyper-V -IncludeManagementTools -Restart
