Thanks for the heads-up ! As i told, i am new to Suse Virtualization / Harvester, just doing some quick p.o.c. and completely missed the troubleshooting part of the manual.
And nothing wrong getting help from random guys on the internet, i was just pointing out that any recommended solution should be validated (i mean, "is this 1:1 applicable in my case" "what effect can it have" etc) before blindly typing something into a root shell 🙂
