Hi Kevin,
can you please tell us what version of hosted-engine are you running?
rpm -q ovirt-hosted-engine-ha
Also, do I understand it correctly that the engine VM is running, but you see bad status when you execute the hosted-engine --vm-status command?
If that is so, can you give us current logs from /var/log/ovirt-hosted-engine-ha?
