Jon, I've been updating the Ansible to move our physical hosts from Centos6 to Centos7, now that's done I'll run through an HA setup and post answers (probably after easter break).

I have 3 compute nodes each with 3 NICS (management, VMs traffic, storage), one management node with just a single NIC connection in the management network and a separate NFS server. I have tried with and without the new Host HA KVM in CS v4.11 as from what I have read even without enabling the new Host HA KVM when you power off or reboot a compute node your VMs should still migrate. I have tried powering off a compute node, pulling the power lead, removing the management and NFS network cables and the management server just seems to carry on as if nothing has happened. Could someone explain exactly how HA is meant to work so I can look at where it is going wrong.
