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.
