Before you can connect virtual machines to virtual functions, use the vSphere Web Client to enable SR-IOV and set the number of virtual functions on your host.
Procedure
Results
The virtual functions become active on the NIC port represented by the physical adapter entry. They appear in the PCI Devices list in the Settings tab for the host.
You can use the esxcli network sriovnic vCLI commands to examine the configuration of virtual functions on the host.
What to do next
Associate a virtual machine with a virtual function through an SR-IOV passthrough network adapter.
