Issue Description:
The guest OS displays a black screen when attempting to boot AlmaLinux 8/9 and RHEL 9 on a VirtualBox VM running on an AMD EPYC 9454P host. No graphical output or login prompt is visible.
Steps to Reproduce:
Create a new AlmaLinux 8 virtual machine in VirtualBox.
Configure the VM's hardware settings, assigning an appropriate amount of RAM and CPU cores.
Attach a virtual hard disk image containing the AlmaLinux 8 installation media.
Start the VM
.
Observe that the VM boots to a black screen.
Expected Behavior:
The VM should display the AlmaLinux 8 boot splash screen and eventually present the login prompt
.

The issue persists even after updating VirtualBox 7.0, and 7.1 Beta 2

The "installation media" should be an iso file. You insert it in the VM's Virtual CD/DVD Drive (NOT on a Virtual Hard Drive) and then boot the VM to install the Operating System, same as you would with a CD/DVD installer on a real computer.
The process is described in the VirtualBox User Manual (Section 2.8.1 Page 14)

Tried in Arch Linux also.

The processor is AMD EPYC 9454P 48-Core Processor
If i do cat /sys/module/kvm_amd/parameters/nested the output is 1
but
VMs hang with the Enable Nested VT-x/AMD-V
and
Enable Nested Paging
settings
Is is something to do with VirtualBox detecting the wrong CPU ?
00:00:00.703071 CPUM: Matched host CPU AMD 0x19/0x11/0x1 AMD_Unknown with CPU DB entry 'AMD Ryzen 7 1800X Eight-Core' (AMD 0x17/0x1/0x1 AMD_Zen_Ryzen)
in VBox.log
as my issue is different should I open a new defect ?
Sorry
Host OS: AlmaLinux 8
