Prepare to Enable Virtualization (Oracle Linux)

1. Prepare the adapter to configure the firmware for virtualization and run in an Oracle Virtual Server with OVM 4.3.1 using UEK4.
2. Enable the number of VFs in the VMs, using the pflash command.

   pflash is the name of the firmware update tool. See Update the Firmware (Oracle Linux) for more information.

   pflash -d  device-path  num_vfs 4

   where device-path is the path to flash device, in [domain:]<bus>:<slot>.<func> format. . The sample output above displays the value num_vfs 4 which enables four VFs. Valid num_vfs include 0,1,2,4,8,16, or 32 to show or configure supported number of VFs.

   The value 0 reverts back to a nonvirtualized mode or PF. This setting is persistent with reboots.

3. Reboot the server to verify the new configuration.

   pflash -d  device-path  num_vfs

4. Enable virtualization.
