Live CD boot - blank screen

I am using a KVM based virtual machine using virgil-3d. When booting with the endeavour os live CD, the VM is able to boot but then I get a blank screen. I have tried passing on acpi=off and nomodeset while booting. But it’s not working.

My qemu cmd line for the graphics configuration looks like this:

-vga virtio
-display gtk,grab-on-hover=on,gl=on

My question is are there any ways to stop the GUI from starting up using the live cd? If not, what’s going wrong here? With the same configuration, I am able to boot from a Manjaro/KDE Neon Live CD without any problems.

Thanks,
Sanjay

When I remove the 3D acceleration part by removing gl=on, the system boots up fine.

Give the program you use some log output?
So we could see what is failing?
EnOS ISO bots fine with virtual box and also qemu is not a known issue.

I installed endeavouros by disabling 3D acceleration. I enabled 3D acceleration again and the screen goes blank again. There are no errors in the Xorg.0.log file and it looks like this (sorry I am unable to upload the file):
