Detach desired VFs:
# virsh nodedev-dettach pci_0000_16_04_0 Device pci_0000_16_04_0
detached <-- VF LOM Port 0 (Function 0) # virsh nodedev-dettach
pci_0000_16_08_0 Device pci_0000_16_08_0 detached <-- VF LOM Port 1
(Function 1)
Example 2 (using only one VF per physical port):
SLES 11.x Xen: - View Emulex PCI devices with the lspci command:
# lspci | grep Emulex 16:00.0 Ethernet controller: Emulex

Port 1 (Function 1)
10. Use the Virtual Machine Manager GUI to attach the VF (step 5 on page 839) to the
guest operating system by using the add physical device option.
Note: To reconfigure a system that is already set up, remove the attached VF from
the guest operating system by selecting the VF and using the remove option.
See the documentation for the host operating system for information on
using the Virtual Machine Manager to attach and remove virtual interfaces.
11. Start the RHEL 6.x guest operating system. Once the guest operating system is
booted, use the lspci command to confirm the visibility of the NIC function. The
output shows a NIC function, for example:
03:00.0 Ethernet controller: Emulex Corp. Emulex OneConnect 10Gb
NIC (be3)
12. The Ethernet driver automatically loads with the out-of-box driver, and creates the
network interfaces. Use the ifconfig command to verify that the interface is created.
13. After configuring the network interfaces with proper IP addresses, you can send
and receive network traffic from the VM. See the documentation for the host and
guest operating systems for information on network configuration.
