8.3. LACP 用の OVS DPDK ボンディングの設定

次の目的は、OVS DPDK 内で LACP ボンディングを設定することです。

8.3.1. Open vSwitch を準備する
リンクのコピー

  1. Huge Page やその他の値が RHEL で設定されていることを確認します。 

    [root@baremetal bonding]# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.10.0-693.17.1.el7.x86_64 root=UUID=fa414390-f78d-49d4-a164-54615a32977b ro console=tty0

  2. DPDK 用に OVS を設定します。 

    [root@baremetal bonding]# ovs-vsctl list Open_vSwitch | grep other
other_config        : {}
[root@baremetal bonding]# ovs-vsctl --no-wait set Open_vSwitch . other_config:pmd-cpu-mask=0x17c0017c
[root@baremetal bonding]# ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-lcore-mask=0x00000001
[root@baremetal bonding]# ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-init="true"
    Copy to Clipboard Toggle word wrap

  3. インターフェイスをユーザースペースに切り替えます。 

    [root@baremetal bonding]# ethtool -i p1p1 | grep bus
bus-info: 0000:04:00.0
[root@baremetal bonding]# ethtool -i p1p2 | grep bus
bus-info: 0000:04:00.1
[root@baremetal bonding]# driverctl set-override 0000:04:00.0 vfio-pci
[root@baremetal bonding]# driverctl set-override 0000:04:00.1 vfio-pci
    Copy to Clipboard Toggle word wrap

  4. Open vSwitch、journalctl -u ovs-vswitchd -f & を再起動し、バックグラウンドで実行します。
