Manual Intervention

As part of the CloudStack HA design, CloudStack HA must not restart a VM if it cannot be sure that it can be done safely.  In those cases, the VM stays in a transitional state.  In those cases, the system administrator can manually intervene by checking to make sure the VM or the host the VM is shutdown, and then calling CloudStack to stop the VM with forced stop flag set to true.  When called in this manner, CloudStack attempts to stop the VM but will continue to release resources even if any of the operations to the hypervisor host cannot be completed.  After doing this, CloudStack HA will stop any attempt to restart the VM and it can be restarted by the administrator.
