I gave it many tries and only when manually adding your
recommended firewall-cmd command, I was able to go one step
further in the run.
Next issue is there :

So here is the time I have to admit I'm trying to run all this on
a *very* humble machine, with only 4Gb of RAM, that may sound
ridiculous but I am prepared to wait for days between each command
return and mouse click, as long as everything is doing its job
(slowly).
Not being able to allocate memory is blocking me from even testing
Lago.
Wouldn't be somewhere I could tweak some limits?
Of course, but I don't such low value would suffice. You can change
the template - basic_suite_3.6/LagoInitFile.in
Thank you Nadav for your answer about networking.
Thank you Yaniv as always helpful, because your hint worked : I reduced
the values of memory settings in the Lago init file and ran everything
from scratch : at first, it got stuck for hours with no disk usage
progress (as adviced in the FAQ).
So I stopped everything, and ran a cleanup, then deleted the
/var/lib/lago/somewhere/rpm/cache/blahblah, and also rm -fr the
deployment dir.
Then ran again, and it seems that everything until the tests went OK.
Now in my processes, I can see qemu processes running the engine, the
host0, host1 and storage.
virsh # list
Id Name State
----------------------------------------------------
1 f8b91b68-lago_basic_suite_3_6_engine running
2 f8b91b68-lago_basic_suite_3_6_host1 running
3 f8b91b68-lago_basic_suite_3_6_host0 running
4 f8b91b68-lago_basic_suite_3_6_storage running
But the first test (engine initialization) is failing with an issue
related to paramiko (see below).
Apart from googling it, I had no idea what paramiko was.
Anyway, as it leads to test 001 failing, then eventually complete stop,
I have to know how to correct this.
I already checked that I have the paramiko RPM installed.

Many stackoverflow answers seem to say that the fix is easy, but I have
no clue where to put these settings?
