The Sriov Support field should report Supported as in Figure 6.
Figure 6: Verify NIC support for SR-IOV
If the Get-NetAdapterSriov does not report “Supported” and your NIC should support SR-IOV, check the following:
• Make sure that your server supports SR-IOV.
• Make sure that your server has the latest System ROM and firmware.
If your server supports SR-IOV and the firmware is up-to-date, check the following:
• If you see “Missing ACS,” try plugging in the SR-IOV NIC in a different PCI Express slot. It is possible that a PCI Express
Switch on the server does not support SR-IOV.
• If you see “Missing PF Driver,” confirm that your NIC supports Windows 2012 SR-IOV, and then run Windows Update and
upgrade your NIC drivers.
• If you see “No bus resources,” try disabling unused devices from the System BIOS settings.
• If you see “No IOMMU support,” verify the following:
– Confirm that the Hyper-V role is enabled.
– Confirm that SR-IOV is enabled in the RBSU. For instructions on enabling SR-IOV, see the Configure System section.
