Improvement/UI : Cloudstack Should validate if OOBM is enabled before enabling HA on the KVM host #13605
Description
problem
Cloudstack should validate if OOBM is enabled before enabling HA on the KVM host
versions
ACS 4.22.1
The steps to reproduce the bug
Currently there are 2 type os HA Host ha and vm ha.
Many users think by enabling host ha they achieve vm ha also
Currently, the host ha can be enabled without cross checking if the OOBM is enabled
https://cloudstack.apache.org/api/apidocs-4.22/apis/enableHAForHost.html
OOBM
Cloudstack should not allow to enable host ha if the OOBM is not enabled or configured
What to do about it?
We can check if oobm is enabled for the host via the api and provide a pop up to the admin user to enable it they try to enable host ha
https://cloudstack.apache.org/api/apidocs-4.22/apis/listHosts.html
Cloudstack should not allow to enable host ha if the OOBM is not enabled or configured

I would like to work on this UI improvement. Here is my proposed implementation plan:
enableHA/configureHAForHostaction in the host management view. Before dispatching the API call, inspect the host's Out-of-Band Management (OOBM) status (outofbandmanagement.enabled/ power state).ConfigureHAForHostCmd/HAConfigManagerImplalso performs a server-side check so the API gracefully rejects HA enablement on KVM hosts lacking OOBM configuration.DaanHoogland commentedon Jul 20, 2026
@kiranchavala @Chinmay048 , is this applicable to older versions?
