c. From lspci, select the 10G NIC sequence number for which SR-IOV
is required. For example:
~ # lspci | grep -i Broadcom 0000:03:00.0 Network
Controllers: Broadcom Corporation NetXtreme II BCM57810
10 Gigabit Ethernet [vmnic0]
Following is a sample output.
0000:03:00.1 Network Controllers: Broadcom Corporation
NetXtreme II BCM57810 10 Gigabit Ethernet [vmnic1]

d. In the driver, enable SR-IOV by using the max_vfs parameter and
passing a list containing the quantity of VFs for each port. In the BIOS,
ensure that the quantity of VFs per PF parameter is configured with a
minimum of the required quantity of VFs. Each PF port supports a
maximum of 64 VFs; the minimum quantity is 1. For example:
~ # esxcli system module parameters set -m bnx2x -p
"max_vfs=64, 64"
e. Restart the system.
4. Install the QLogic drivers for the adapters detected in the VM. Use the latest
drivers available from your vendor for the host OS (do not use the inbox
drivers). The same driver version must be installed on the host and the VM.
Verifying that SR-IOV is Operational
Follow the appropriate steps for Hyper-V, VMware vSphere, or ESXi CLI.
To verify SR-IOV in Hyper-V Manager:
1. Start the VM.
2. In Hyper-V Manager, select the adapter and select the VM in the Virtual
Machines list.
3. Click the Networking tab at the bottom of the window and view the adapter
status.
To verify SR-IOV in VMware vSphere 6.0 U2 Web Client:
1. Confirm that the VFs appear as regular VMDirectPath devices by selecting
Host, Manage, Settings, Hardware, and then PCI Devices.
2. Right-click VM, Edit settings, New Device, Select Network, and Add.
Click New Network and then select SR-IOV as the adapter type. Click OK.
