Truenas scale VM - VNC is failing after couple of seconds

[alamakotaakotmakaca]

hi,

I'm trying to install my first virtual machine. Unfortunately, after starting VNC it works for a while and then dies (black screen).

TrueNAS Scale 22.13.3, new installation
VNC configuration:
Port: 5900, 5901, total random
Resolution: Various tested
Bind: All that was
Password: None

Browser: FireFox, Edge, RealVNC Viewer

Errors occurred both when trying to install Ubuntu 22 and Debian 12.

I searched google and the forum, tested different combinations. I'm out of ideas and don't know what to do next.

It looks like I've managed to solve the problem. The reason was not VNC, but kernel panic.

It seems that the minimum ram setting (I was set to 512MiB) was causing panic.
I should have tried installing with terminal instead of graphical mode right after the problems started
