Enable Virtualization (Oracle Linux)

1. Locate the device(s) on the server.

   #lspci -d :2088 
   a0:00.0 Infiniband controller: Oracle/SUN Device 2088 (rev 03) 
      

   where 2088 is the vendor ID.

2. Find the directory to set the number of VFs using the device ID from Step 2.

   # find /sys/devices | egrep "a0:00.0" | head -1 
   /sys/devices/pci0000:80/0000:80:03.0/0000:a0:00.0
     

3. Change to the directory.

    
   # cd /sys/devices/pci0000:80/0000:80:03.0/0000:a0:00.0
     

4. Type the number of VFs into the directory sriov_numvfs.

   # echo 4  sriov_numvfs
     

   where 4 is the sample number of VFs.

5. Change to the directory.

    
   # cd  /sys/bus/pci/drivers/pci-stub/
     

6. Type the device ID to the new_idfile.

   # echo "108e 2089" > /sys/bus/pci/drivers/pci-stub/new_id
     

   Repeat Steps 3 to Step 6 after each server reboot.
