Hi, I have a Wallaby cluster with 5 controller and 130 compute node. Host OS: Rocky 8.7 Deploy tool: Kolla-ansbile kolla_base_distro(container images): centos Network Mode：**OVN** After completing the deployment, the functionality for creating a single instance works as expected, and instances are created successfully. However, the process is extremely slow. When attempting to create instances in bulk, the operation fails on a large scale. During this time, I observed that the ovsdb-server is consuming close to 100% CPU usage. Even without any tasks being processed, the CPU usage remains consistently around 90%, just from the cluster's regular operations. I redeployed the cluster and switched the network mode to Open vSwitch (OVS), and everything works as expected with normal performance. Could anyone offer guidance on what might be causing this issue? I’m aiming to use the OVN mode with Kolla in a large-scale OpenStack cluster (100+ nodes). What configuration or adjustments would I need to make? Thank you in advance for your help! Han Guangyu
