I found in broker log the message
Thread-1730::ERROR::2015-10-22
17:31:47,016::listener::192::ovirt_hosted_engine_ha.broker.listener.ConnectionHandler::(handle)
Error handling request, data: 'set-storage-domain FilesystemBackend
dom_type=nfs3 sd_uuid=f53854cd-8767-4011-9564-36dc36e0a5d1'
Traceback (most recent call last):
...
BackendFailureException: path to storage domain
f53854cd-8767-4011-9564-36dc36e0a5d1 not found in /rhev/data-center/mnt

so probably the NFS part was not in lace yet when the broker attempted to
start?
I saw that actually I had now

[root at ovc71 ovirt-hosted-engine-ha]# ll
/rhev/data-center/mnt/ovc71.localdomain.local:_NFS__DOMAIN
total 0
-rwxr-xr-x. 1 vdsm kvm  0 Oct 23 16:46 __DIRECT_IO_TEST__
drwxr-xr-x. 5 vdsm kvm 47 Oct 22 15:49 f53854cd-8767-4011-9564-36dc36e0a5d1

and I was able to run

systemctl start ovirt-ha-broker.service
and verify it correctly started.
and the same for
systemctl start ovirt-ha-agent

after a couple of minutes the sh engine VM was powered on and I was able to
access web admin portal.

But if I try to connect to its console with

[root at ovc71 ovirt-hosted-engine-ha]# hosted-engine --add-console-password
Enter password:
code = 0
message = 'Done'

and then
# remote-viewer --spice-ca-file=/etc/pki/vdsm/libvirt-spice/ca-cert.pem
spice://localhost?tls-port=5900 --spice-host-subject="C=EN, L=Test, O=Test,

I get an error window with
