I'm struggling with the same problem (I say struggling because I'm still
having stability issues for what i consider a stable cluster) but you can:
- create a replica 3 engine gluster volume
- create replica 2 data, iso and export volumes

Deploy the hosted-engine on the first VM (with the engine volume) froom the
CLI, then log in Ovirt admin, enable gluster support, install *and deploy*
from the GUI host2 and host3 (where the engine bricks are) and then install
host4 without deploying. This should get you the 4 hosts online, but the
engine will run only on the first 3
