SR-IOV - Windows Server 2016

[synth3tix]

Hi friends,

Im not sure where to go from here, so Im gonna ask you guys - maybe someone can help/enlighten me.

As the title suggests, I wanted to activate and use SR-IOV on our Virtualization-Host. Its a Dell Poweredge R740 running Windows Server 2016 with an Intel X710 DA2, which supports SR-IOV.

What I did:

1. Server UEFI
- Activated "SR-IOV Global Enable"
- Activated Virtualization mode "SR-IOV" for the Intel card in the device settings of the server UEFI

2. Windows Server 2016

- Enable-Netadaptersriov -Name X710_Port1
- Enable-Netadaptersriov -Name X710_Port2

3. VMs
- Activated the SR-IOV feature in the virtual nic settings


A quick "Get-NetAdapterSriov" gave me this:

Name : X710_Port2
InterfaceDescription : Intel(R) Ethernet 10G X710 rNDC
Enabled : True
SriovSupport : Supported
SwitchName : DefaultSwitchName
NumVFs : 128

Name : X710_Port1
InterfaceDescription : Intel(R) Ethernet 10G 4P X710/I350 rNDC
Enabled : True
SriovSupport : Supported
SwitchName : DefaultSwitchName
NumVFs : 128


When I checked the status of the VM with "Get-VMNetworkAdapter WSUS | fl *iov*, *status*, *virtualfunction*". I got this:

IovWeight : 100
IovQueuePairsRequested : 1
IovInterruptModeration : Default
IovQueuePairsAssigned : 0
IovUsage : 0
StatusDescription : {OK}
Status : {Ok}
VirtualFunction :


Is this working as intended? Because on screenshots on some other guy's blog, I saw some stuff behind VirtualFunction and now Im not sure what is going on.


Thank you in advance for any kind of input.


Best Regards,

Constantin
