82576NS LINUX DRIVER

Numerical values from the lspci output shown in Section The following procedure is using example data. This option will only affect the persistent XML, even if the domain is running. That means the driver is already loaded. Before loading the driver, make sure the card is properly detected by running lspci.

If the domain is inactive, the operation will fail. This option will always add the device to the domain’s persistent XML.

In order to do so, you need to collect some data first. Use rmmod to unload linud driver. This option will only affect the persistent XML, even if the domain is running. The device is not persisted in the XML and won’t be available in the guest on next boot. If the domain is inactive, the device is added to 82576nd persistent XML and will be available on next boot. Make sure to replace the example value igb by a value appropriate for your driver.

PFs also have the ability to move data. The first two entries represent the PFs whereas the other entries represent the VFs. In case a device is already attached to the 82567ns, it cannot be attached to a guest.

Specify the data you acquired in the previous step here.

Each of these “pseudo-devices” can be assigned to a VM Guest. In the following example a check for the igb driver for the Intel NS network card returns a result.

This option will only affect a running domain.

The following procedure is using example data. Reboot the linuxx and check if the SR-IOV driver is loaded by re-running the lspci command from the first step of this procedure. Numerical values from the lspci output shown in Section The theoretical maximum for VFs is per device consequently the maximum for a dual port Ethernet card would be Make sure to replace it by appropriate data from your setup.

The minimal oinux of the file needs to look like the following:.

In addition, if the domain is running, it will be hotplugged. To make it available for guests, detach it from the host first:. PFs are full PCIe functions used to manage and configure the device.

Intel Corporation Virtual Function rev 01 VFs do not get a fixed MAC address, it changes everytime the host reboots. That means the driver is already loaded.

Now make sure the driver is loaded on boot. This option affects the current state of the domain.

The following example shows the lspci output for the dual port Intel NS network card:. Intel Corporation Virtual Function rev 01 [ If the command returns nothing, the driver is not loaded.

Make sure to replace the example values igbigbvf and igb by 825576ns appropriate for your driver. VFs lack the configuration and management part—they only have the ability to move data and a reduced set of configuration functions. Configure the driver by adding the number of VFs you would like to make available and—if necessary— by blacklisting the non-SR-IOV driver:. The following example shows the lspci output for the dual port Intel NS network card:
