</span>There are two different notions of host maintenance:<br>
<br>
1. in the engine, meaning the engine will migrate away VMs from<br>
this host, not start new ones on it, etc. This applies to all<br>
hosts, not just hosted-engine ones<br>
<br>
2. in ovirt-hosted-engine-ha, the high availability daemons.<br>
Here it means similar things, but applies only to the hosted<br>
engine vm, and is maintained in the HE shared storage (not in<br>
the engine db).<br>

</span>This one does (2.).<br>

<br>
</span>In the past, this did only (1.), but now it does both.<br>
