Leap 15.3 hangs after login on W10 VirtualBox, 15.1 & 15.2 login successfully

Greetings, I’m trying to install for a test Leap 15.3 in W10 Virtual Box (6.1), but after login, all I get is a screen with the light bulb, but nothing more. (I would add an screenshot, but the forum doesn’t seem to acknowledge imgur or imgbb) It doesn’t react to any key press I have attempted, and I have let it run for 30 min or so and it doesn’t change.https://ibb.co/HYfDjD0https://ibb.co/HYfDjD0

However, Leap 15.1 and Leap 15.2 install and run successfully in the same environment, and I have made sure that I configure the installation in the same way in all instances.

Does Leap 15.3 need something different to install, compared to previous versions? I was able to run a 15.3 Live USB on this computer, but it was really slow, as in taking 15 seconds to maximize a window, so it wasn’t a viable test environment.

I tried searching in here for possible posts with the same issue, but no luck.

In a secondary question, what is the intended difference between openSUSE-Leap-15.3-2-NET-x86_64-Current.iso and openSUSE-Leap-15.3-NET-x86_64-Current.iso (in http://download.opensuse.org/distribution/leap/15.3/iso), what is the purpose of -2 in the name of the file. Also I use ‘intended’ for a reason, because if I try to download the second one, I actually get the same file as the first link (openSUSE-Leap-15.3-2-NET-x86_64-Build24.5-Media.iso)

Have you tried copying the 15.2 VDI and upgrading it to 15.3?

You did not say what desktop, file system, and options you installed with.

Does the right ctrl + insert + f4 to get a console? (you might have to try 3 or 4 times).

If so - what VGA did you select (I use VMSVGA) for the Virtual Machine - How much ram, cpu’s? are the Virtualzations options enabled under SYSTEM?

I’m actually considering doing this, just cloned the 15.2 and checking the instructions.

I left almost all the default values for the installation itself. I only changed my keyboard layout, country and city. Desktop currently is KDE, but there is no change with GNOME.

For the VM, also mostly the default ones, specially for the virtualizations options. 4GB of RAM, 45GB HD, 1 CPU (1 works for 15.1 & 15.2)

Previously tested with 2 CPUs, no dice, now I just tested started it with 4 CPUs and it started successfully. It is a hidden requirement? I don’t see anything of the sort in Hardware requirements 15.3 - openSUSE Wiki

I don’t think it is a matter of just processing power, otherwise it would have eventually started, but I have left it running for 20+ min with 1 CPU and there is no (visible) change/advance.

KDE uses a lot of CPU - I would do a minimum of 2

Change the VGA mode - the default leaves a blank screen - you have to zypper rm virtualbox-guest-x11 on some installs.

you have to do that in a opensuse terminal (right ctrl + insert + f4) login as root - reboot after the removal.
