Thanks Gianluca,
So I installed the engine into a separate VM, and didn't go down the
hosted-engine path, although if I was to look at this with physical hosts,
this seems like a really good approach.
To answer Michal's question from earlier, the nested VM inside the oVirt
Hypervisors has been up for 23+ hours and it has not progressed past the
Bios.
Also, with respect to the vdsm-hooks, here's a list.

I'm running ESXi 5.5. For the hypervisor VMs I've set the "Expose Hardware
Assisted Virtualization to the guest OS"
Hypervisor VMs are running CentOS 7.3
