Configuring Intel 82599 VF NICs on the KVM platform
This section uses HP 360Gen8 and VMware Fedora 17 as an example. You can use the same method
to configure VF NICs for the CentOS system.
To configure Intel 82599 VF NICs on the KVM platform:
1.
Log in to the server as a root user.
2.
Log in to the virtual platform and view information about the Intel 82599 NIC. The command
output varies with NIC numbers.
~ # lspci | grep -i intel | grep -i 'ethernet\|network'
Figure 96 One Intel 82599 NIC, providing a total of two physical ports
Figure 97 Two Intel 82599 NICs, providing a total of four physical ports
3.
Add the content in the red circle to /boot/grub2/grub.cfg to enable the IOMMU on the core, as
shown in
.
The IOMMU on the core is disabled for the Fedora17 system by default.
Figure 98 Changing the startup options on the core
4.
Create an ixgbe.conf file in /etc/modprobe.d to configure the VF NICs.
Use the option max_vfs to specify the number of VF NICs for each physical port. The default VF
NIC driver supports only max_vfs=X. You can only configure the same number of VF NICs for all
ports.
