A Red Hat training course is available for Red Hat OpenStack Platform
Chapter 9. Deploying different bond modes with OVS DPDK
Use this procedure to deploy different bond modes with OVS-DPDK in Red Hat OpenStack Platform.
9.1. Solution
Make the following changes to the compute.yaml
environment file. Note that this example also sets the MTU value to 2000.
(...) - type: ovs_user_bridge name: br-link mtu: 2000 use_dhcp: false members: - type: ovs_dpdk_bond name: dpdkbond0 ovs_options: "bond_mode=balance-slb" mtu: 2000 ovs_extra: - set interface dpdk0 mtu_request=$MTU - set interface dpdk1 mtu_request=$MTU members: - type: ovs_dpdk_port name: dpdk0 members: - type: interface name: p1p2 - type: ovs_dpdk_port name: dpdk1 members: - type: interface name: p1p1 (...)
Deploy or redeploy the overcloud with the template changes made above. When complete, perform the following steps on an overcloud node.
Verify the os-net-config
configuration:
cat /etc/os-net-config/config.json | python -m json.tool (...) { "members": [ { "members": [ { "members": [ { "name": "p1p2", "type": "interface" } ], "name": "dpdk0", "type": "ovs_dpdk_port" }, { "members": [ { "name": "p1p1", "type": "interface" } ], "name": "dpdk1", "type": "ovs_dpdk_port" } ], "mtu": 2000, "name": "dpdkbond0", "ovs_extra": [ "set interface dpdk0 mtu_request=$MTU", "set interface dpdk1 mtu_request=$MTU" ], "ovs_options": "bond_mode=balance-slb", "type": "ovs_dpdk_bond" } ], "mtu": 2000, "name": "br-link", "type": "ovs_user_bridge", "use_dhcp": false }, (...)
Verify the bond:
