Neutron 集成 DPDK
这里介绍Neutron集成DPDK时，Neutron相关的配置，计算节点用DPDK加速【虚机到OVS, 物理网卡到OVS】
neutron-openvswitch-agent +DPDK
Compute Node：
1 # 配置 /etc/neutron/plugins/ml2/openvswitch_agent.ini 2 ##为加速Overlay, 物理网卡加入br-tun, IP配置到br-tun 3 4 [ovs] 5 vhostuser_socket_dir = /var/run/openvswitch/ 6 datapath_type = netdev 7 bridge_mappings = physnet1:br-eth1 8 tunnel_bridge = br-tun 9 local_ip = 192.168.200.132 10 of_interface = ovs-ofctl
创建虚机
OVS-DPDK uses hugepages to communicate with guests, before you boot a VM with OVS-DPDK you will need to create a flavor that requests hugepages.
nova flavor-key <FLAVOR> set hw:mem_page_size=large
