Hello In my cloudstack setup, I have three KVM hypervisors out of which two hypervisors are dedicated to Root/admin account and the third is not dedicated. When I enable the maintenance mode on the dedicated hypervisor, it will always migrate the vm's from dedicated to non dedicated hypervisor but not to second dedicated hypervisor. I dont think this is the expected behavior. Can any one please verify? The dedicated hypervisors will be added to avoid set and the deployment planning manager skips these hypervisors.
If I dedicate the third hypervisor to different domain and enable the maintenance mode on the first hypervisor then all the vm's will be stopped instead of migrating to second dedicated hypervisor of the same domain/account. I have highlighted the necessary logs in red. You can see from the logs that host with id 17 and 20 are dedicated but not 26. When maintenance mode is enabled on host id 20, it skips 17 and 20 and migrates vm's to host id 26 2019-08-12 14:35:23,754 DEBUG [c.c.d.DeploymentPlanningManagerImpl] (Work-Job-Executor-9:ctx-786e4f7a
