[OVS] OVS-DPDK 실행

환경 변수 추가와 권한 문제로 root에서 실행하는 것을 추천합니다.

1. 초기화

pkill -9 ovs
rm -rf /usr/local/var/run/openvswitch/
rm -rf /usr/local/etc/openvswitch/
rm -f /usr/local/etc/openvswitch/conf.db
mkdir -p /usr/local/var/run/openvswitch/
mkdir -p /usr/local/etc/openvswitch/
rm -f /tmp/conf.db

2. 환경변수 추가 및 ovsdb 설정

export PATH=$PATH:/usr/local/share/openvswitch/scripts
export DB_SOCK=/usr/local/var/run/openvswitch/db.sock
ovsdb-tool create /usr/local/etc/openvswitch/conf.db /usr/local/share/openvswitch/vswitch.ovsschema
ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock --remote=db:Open_vSwitch,Open_vSwitch,manager_options --pidfile --detach

3. DPDK 사용을 위한 OVS 설정 및 시작

ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-init=true
ovs-ctl --no-ovsdb-server --db-sock="$DB_SOCK" start

4. Bridge 생성 및 DPDK Port 연결

ovs-vsctl add-port [bridge] [portname] -- set Interface [portname] type=dpdk options:dpdk-devargs=[dpdk를 bind 한 NIC]

ovs-vsctl add-br br0 -- set bridge br0 datapath_type=netdev
ovs-vsctl add-port br0 dpdk0 -- set Interface dpdk0 type=dpdk options:dpdk-devargs=0000:05:00
ovs-vsctl add-port br0 dpdk1 -- set Interface dpdk1 type=dpdk options:dpdk-devargs=0000:05:01

5. Flow Rule 

ovs-vsctl add-flow br0 in_port=dpdk0,action=output:dpdk1

6. 오류 해결
