Hello,
I have updated an environment from 4.2.8 to 4.3.1.
During setup I selected:

          --== PRODUCT OPTIONS ==--
         
          Set up Cinderlib integration
          (Currently in tech preview. For more info - 
          (Yes, No) [No]: Yes
. . .
          --== DATABASE CONFIGURATION ==--
         
          Where is the ovirt cinderlib database located? (Local, Remote) [Local]: 
          Setup can configure the local postgresql server automatically for the CinderLib to run. This may conflict with existing applications.
          Would you like Setup to automatically configure postgresql and create CinderLib database, or prefer to perform that manually? (Automatic, Manual) [Automatic]: 
. . .
          --== CONFIGURATION PREVIEW ==--    
. . .
          CinderLib database secured connection   : False
          CinderLib database user name            : ovirt_cinderlib
          CinderLib database name                 : ovirt_cinderlib
          CinderLib database host                 : localhost
          CinderLib database port                 : 5432
          CinderLib database host name validation : False
          Set up Cinderlib integration            : True
          Configure local CinderLib database      : True

at the end I upgraded cluster and dc compatibility version to 4.3.
When I go in the UI and add storage domain, in "Domain Function" field I don't see the "ManagedBlockStorage" between the available ones  

I see that the RDBMS has been created, but empty... is it the expected result?

-bash-4.2$ psql ovirt_cinderlib
psql (9.2.24, server 10.6)
WARNING: psql version 9.2, server version 10.0.
         Some psql features might not work.
Type "help" for help.

ovirt_cinderlib=# \d
No relations found.
ovirt_cinderlib=# 

Any hint about enabling/testing cinderlib integration with 4.3.1?
Current packages on engine:

[root@ovmgr1 ~]# rpm -qa | grep -i cinder
openstack-java-cinder-model-3.2.5-1.el7.noarch
ovirt-engine-setup-plugin-cinderlib-4.3.1.1-1.el7.noarch
openstack-java-cinder-client-3.2.5-1.el7.noarch
[root@ovmgr1 ~]# 

and "yum search cinder" command doesn't give any more packages than those already installed 
Thanks in advance,
Gianluca
