SR-IOV Configuration

Nova

On each compute you have to associate the Virtual Functions available to each Physical Network. You do it by configuring pci_passthrough_whitelist in /etc/nova/noca.conf

For example:

pci_passthrough_whitelist = {"address":"*:0a:00.*","physical_network":"physnet1"}

This will associate any VF with address that includes ':0a:00.' in it's address to the Physical network physnet1

After configuring the white list you have to restart nova-compute service.

Neutron Server

Using ML2 Neutron plugin modify /etc/neutron/plugins/ml2/ml2_conf.ini:

[ml2]
tenant_network_types = vlan
type_drivers = vlan
mechanism_drivers = openvswitch,sriovnicswitch
[ml2_type_vlan]
network_vlan_ranges = default:2:100
[securitygroup]
firewall_driver = neutron.agent.firewall.NoopFirewallDriver

Make sure /etc/neutron/plugins/ml2/ml2_conf_sriov.ini has the following section:

[ml2_sriov]
agent_required = True

Neutron server should be run with the two configuration files /etc/neutron/plugins/ml2/ml2_conf.in and /etc/neutron/plugins/ml2/ml2_conf_sriov.ini

neutron-server --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini --config-file /etc/neutron/plugins/ml2/ml2_conf_sriov.ini
