But you still have problems?

Do you have on the host an interface 'ovirtmgmt'?

What do you see in the web admin? mark the host -> Network Interfaces ->
Setup host networks.

If the storage relies on the network (likely), perhaps first fix network

If you do not find there 'ovirtmgmt', not sure.

You can check also /var/log/ovirt-hosted-engine-setup on the host,
as well as normal system log (/var/log/syslog or messages or whatever).

Perhaps. Some file sharing site or something.

If you start from a clean machine, it should do all.

If you start from a machine which already has an interface 'ovirtmgmt'
but has problems, iiuc the script will not fix them.
