-- sriov_nic01: Name of the interface
-- sriov_nic01_numvfs: Number of Virtual Functions
-- sriov_nic01_physical_network: Default "physnet1", label for physical network interface belongs to.
-- sriov_unsafe_interrupts: Default False, needs to be set True if your hw platform does not support interrupt remapping
+For single SR-IOV interface setup you can set parameters:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`sriov_nic01_device_name`
+  Name of the Physical Function interface (pF)
+
+`sriov_nic01_numvfs`
+  Number of Virtual Functions (VF), for number of 
+  supported VF check documentation for your network interface card.
+
+`sriov_nic01_physical_network`
+  Default **physnet1**, label for physical network the interface belongs to.
+
+`sriov_unsafe_interrupts`
+  Default **False**, needs to be set **True** if your hw platform does not 
+  support interrupt remapping.
+
+
+Multiple SR-IOV interface setup:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default, the metadata model contains configuration for 1 NIC
+dedicated for SR-IOV, so we need to setup network interfaces like in the
+following example.
