Hi guys.
        
        I'm revisiting my failed attempt to make friends with oVirt -
        novice so go easy on me.
        Deployment fails sooner that what can troubleshoot - at least I
        manged to find in docs so far - and I wanted to ask hot to
        troubleshot such failure as this:
        ...

        I think that last two snippets-blocks, might be most useful -
        but what does it says?
        When 'installer' is finished, there is no aforementioned pool
        however there is:
        -> $ virsh pool-list | grep
        '9ab14cca-78e0-4a8e-8a1b-00e98c300208'
         9ab14cca-78e0-4a8e-8a1b-00e98c300208-1   active   yes
        
        Engine VM remains is up & running,
        How far from successful deployment that is & what would be
        advised to do next?
        
        many thanks, L.
