Adding the Lago devel mailing list.

The download is the reposync phase - which seems to be OK, but then the connection means that for some reason Lago is not serving those RPMs (8585 is the port it should be listening to).

Can you share some logs?

Perhaps something with the Firewall?

I had no idea whether to keep it or not.
I already disabled selinux after having realized it lead to a read only root file system.

About the issue above, no being able to reach some random port would indeed be caused by the firewall, so I'll give it a try.

During RPM installation it should add the relevant rule to the firewalld, btw:

if which firewall-cmd &>/dev/null; then

    firewall-cmd --reload

    firewall-cmd --permanent --zone=public --add-service=ovirtlago

    firewall-cmd --reload

fi

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?
