To ensure that a virtual machine and a physical NIC can exchange data, you must associate a virtual machine with one or more virtual functions.
Before you begin
Verify that the configuration of your environment supports SR-IOV. See SR-IOV Support.
Verify that the virtual functions exist on the host.
Verify that the passthrough networking device for the virtual function is active on the host.
About this task
After you enable the virtual functions on the host, each of them becomes available as a PCI device.
Launch the vSphere Client and log in to a vCenter Server system.
- Select a virtual machine from the inventory panel of the vSphere Client.
- Power off the virtual machine.
- From the Inventory menu, select .
- On the Resources tab, select Memory.
- Select Unlimited.
- On the Hardware tab, click Add.
- Select PCI Device and click Next.
- From the drop-down menu select the virtual function.
- Click Finish.
- Power on the virtual machine.
Adding a virtual function as a PCI device to a virtual machine sets memory reservation to the memory size of the virtual machine.
