Before adding second host, it requires hosted_storage domain to be
imported into the UI. For this to happen we need to atleast add
one domain. With out creating a storage domain you can try adding
the second host and you will be given a message to add the domain
first.

Thanks for clarifications.
It worked smoothly; all the three hosts are now up; going to test
urther functionalities.
Fine!
In the host-deploy logs for the 3 hosts I only see for the third host
(and for the first file of the two ones generated for first host)
these kinds of warning:

Thanks again
Gianluca
you could safely ignore these messages. There are some tuned profiles
which engine tries to set on the node. If those profiles does not exist
on the node engine throws these kind of messages.

Gianluca,<br>
<br>
yes, you are right. Now second and
third host can be directly added from
UI. Before adding the second and third
host please make sure that the
following steps are done for
hyperconverged setup.<br>
<br>
1) On Hosted engine vm run the command
'engine-config -s
AllowClusterWithVirtGlusterEna<wbr>bled=true'<br>
<br>
2) Restart ovirt-engine by running the
command 'service ovirt-engine
restart'<br>
<br>
3) <em>Edit

<br>
4) Create separate storage domains for
each gluster volume. You can see that
hosted_storage gets imported into the
UI automatically when one storage
domain is created in the UI.<br>
<br>
5) Add second and third host from UI.<br>
<br>
Hope this helps <br>
<br>
