Hi Rayn,
- login to your ovirt-engine machine
- edit 
/usr/share/ovirt-engine/engine.ear/components.war/vds/vds_bootstrap.py
- comment out the following:
   836     if not oDeploy.virtExplorer(random_num):
   837         logging.error('virtExplorer test failed')
   838         return False
- reinstall host - add fake_kvm_support = True to your vdsm.conf under 
/etc/vdsm/vdsm.conf
- restart vdsmd service
