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

Cloudstack should not allow to enable host ha if the OOBM is not enabled or configured
