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
