@rhtyd tests looks good, except this one:
```
ERROR: Tests default ha providers list
----------------------------------------------------------------------
Traceback (most recent call last):
File "/marvin/tests/smoke/test_hostha_simulator.py", line 199, in
test_ha_list_providers
response = self.apiclient.listHostHAProviders(cmd)[0]
TypeError: 'NoneType' object has no attribute '__getitem__'
```
Looks like when simulator is not deployed test would fail.

> CloudStack lacks a way to reliably fence a host, the idea of the host-ha
> feature is to provide a general purpose HA framework and implementation
> specific for hypervisor that can use additional mechanism such as OOBM (ipmi
> based power management) to reliably investigate, recover and fencing a host.
> This feature can handle scenarios associated with server crash issues and
> reliable fencing of hosts and HA of VM.
