F40 Beta KDE fails to boot in VirtualBox on Win11

I wanted to test Fedora 40 KDE Spin on VirtualBox, installed on Windows 11 Pro 22631.3447, but it failed to boot.
I used the latest VirtualBox 7.0.16, created new VM with default Fedora template (same problem after increasing RAM and CPU), mounted Beta 1.10 iso image and tried to launch.
During boot, it stopped at some point. I restarted, changed kernel parameters (replaced ‘quiet rhgb’ with ‘verbose’), pressed F10. It got into drkonqi-coredum loop.
I tried 1.14 ISO, but it got into dark screen black screen with single cursor.

I am attaching screen from VB:

Please verify, do you have the same problem.

EDIT:
Managed to test on Kubuntu 22.04.4 LTS, with VirtualBox 7.0.12 - got black screen.

yes, this is a known bug, I can’t find the related bug report right now, but I can provide it later…

EDIT: sorry, the bug I was talking about was about bad rendering, see GTK4 apps render badly on VMware and VirtualBox with 3D acceleration passthrough enabled, which of course is different from not-booting…

try to boot with troubleshoot → safe graphics mode that might help most of the times

I think this is a known bug blocking the f40 release: 2272758 – Illegal instruction errors in libQt6Core

I tested both releases with safe graphics mode option:
iso 1.10 - drkonqi-coredum loop (same like in normal mode)
iso 1.14 - works (in normal mode - black screen with single cursor)

As far as I know virtualbox will not work trying to run guests using wayland.I tried to install the beta awhile back in virtualbox and it would not work.It did install and work well using gnome boxes.I have Arch and EndeavourOS KDE running as guests in virtualbox and they still have the option to use xorg so they both work well.Neither will boot trying to use wayland.

Same issue here, but on real hardware. Using Fedora 40 beta 1.10 KDE iso image on my Acer Spin 1 shows the same core dumps during boot.

This is because beta 1.10 compose is from March 21st and the updated gcc build is only from April 12th or so (see https://bugzilla.redhat.com/show_bug.cgi?id=2272758#c53)
Unfortunately, the beta download on getfedora isn’t updated to link to the latest RC iso. It gets published once and therefore fixes from the Freeze phase don’t land in the publicly available beta image.

So for now, grab the Release Candidate from Index of /pub/alt/stage/40_RC-1.14/Spins/x86_64/iso
(see also Test Results:Fedora 40 RC 1.14 Desktop - Fedora Project Wiki)

Or the latest from Index of /compose/branched/Fedora-40-20240417.n.0/compose/Spins/x86_64/iso

Cool. Now it works. Got it installed successfully. Even tablet stuff works without any issues (so far :wink: ).

Wasn’t aware that images are not updated regularly. Thanks for the URL to get them anyways.
