Is there any way to have HA in a cluster which hosts have not got configured the "Power Management"?

In my scenario I have 2 hosts (v4) on OVH  and a hosted-engine to manage them. Thing is that OVH does not allow direct communication with the hosts IPMI interface. IPMI is only available in the "customer area" under a java applet as that interface is connected to a non accesible network. So, having no access to this interface I find myself in a situation in which I lost all my HA functionality :(

Any help would be more than welcome.
