Hi Anirudh, Per my understanding, for duplex, there is always 1 active node and 1 standby node. The "active/active" or "active/standby" in the document is for "services", not for node. If you try to run "sudo sm-dump" in the standby node, you will find some services are "active", while some services are "standby". For the 2nd question, VMs are running in compute node. And for duplex, both controller nodes are compute nodes also. And the "Active/Standby" is for controller, not for compute function, that is why VMs will run in both node.

As per the document, there can be 2 modes in which HA controllers can be configure i.e. either "active/active" or "active/standby" https://docs.starlingx.io/deploy_install_guides/r2_release/bare_metal/aio_du... * Can someone please suggest the steps to configure Active-Active state? * I have 2 kubernetes pods corresponding to each Openstack Service in Duplex Setup and when I spawn any VM, it goes on any of the two controllers. So, is this the standard implementation in StarlingX? What needs to be done in Active-Standby configuration? * And, what difference it would have on my deployment in terms of functionality?
