Hi, I deploy a new OpenStack cluster OpenStack (version Yoga, Victoria), neutron using "Networking-ovn".
Then, I create 2 VM (VM is installed by iperf3 tool) on the same network, on the same compute node. I test bandwidth between 2 VM, and the result is:
- Bandwidth is 7 Gbps when the port of the VM has a Security Group.
- Bandwidth is 18 Gbps Gbps when the port of the VM doesn't have a Security Group.
Meanwhile, I deploy a new OpenStack cluster OpenStack (version Yoga, Victoria), neutron use "OpenvSwitch".
Then, I create 2 VM (VM is installed by iperf3 tool) on the same network, on the same compute node. I test bandwidth between 2 VM, and the result is:
- Bandwidth is 18 Gbps when the port of the VM has a Security Group.
- Bandwidth is 18 Gbps Gbps when the port of the VM doesn't have a Security Group.
---> I noticed that the bandwidth between 2 VM (the port of the VM has a Security Group) is very low when deploying Neutron using Networking-OVN |

Hello everyone, We have a critical problem with OpenStack using ML2/OVN.
We deploy two new OpenStack clusters OpenStack (both Yoga and Victoria), neutron using ML2/OVN.
We create a new network Geneve, and create 3 VM on that network. VM name test-1, test2 and gw-hn (See video for detail).
VM test-1 and test-2 in the same compute node and test bandwidth between them use iperf3 and result:
- >= 18Gbps if NO PORT in that network is attached security group
- 6Gbps if just only one port in that network is attached security group
Please see detail in video (https://vimeo.com/778784192):
- VM gw-hn is unrelated to VM test-1 and test-2, but if we add a security group for the port of VM gw-hn, bandwidth between VM test-1 and test-2 drops sharply
OpenStack Cluster Version Detail:
- OpenStack Yoga: OVN 22.03.0, Open vSwitch 2.17.0
- OpenStack Victoria: OVN 20.03.2, Open vSwitch 2.13.5 |
