Configure Mechanism Drivers for SR-IOV

Procedure

Configure the sriovnicswitch mechanism driver in the ml2_conf.ini file on each controller.

[ml2] 
tenant_network_types = vlan 
type_drivers = vlan 
mechanism_drivers = openvswitch, sriovnicswitch, extreme_efa 
[ml2_type_vlan] 
network_vlan_ranges = physnet1:2:500

Ensure that sriovnet is configured for the selected network type in the ml2_conf.ini file on each controller.
```
[ml2_type_vlan]
network_vlan_ranges = sriovnet1:100:500,sriovnet2:100:500
```
