Welcome :-)

Can you share logs at this point? Including /var/log/vdsm/* and
/var/log/ovirt-hosted-engine-setup/* . If you have KVM access, you
might manage to get them. Or copy after a reboot.
Also please share your network configuration. Are you using
NetworkManager (IIRC unsupported currently)? DHCP? Static IP conf?

Or it might be a bug.
