What happened?

On an Intel-based system, the kvm_amd kernel module is being probed during boot, resulting in the message:

kvm_amd: CPU 1 isn't AMD or Hygon

This occurs even though:

The system uses an Intel CPU
kvm_intel loads correctly
No AMD-related virtualization should be involved

The message appears immediately before vboxdrv initialization and VirtualBox reports finding KVM symbols:

kvm_amd: CPU 1 isn't AMD or Hygon
vboxdrv: module uses symbol (...) from namespace module:kvm,kvm-amd,kvm-intel
vboxdrv: Found KVM hardware-virtualization symbols

• This behavior was initially reported upstream to the Linux kernel, where it was suggested that the trigger likely comes from VirtualBox (vboxdrv) interacting with KVM symbols.
• The issue is harmless but creates confusing and unnecessary log noise.
• Blacklisting kvm_amd prevents the message, suggesting it is not required for VirtualBox operation on Intel systems.

How can we reproduce this?

1- Install VirtualBox on an Intel-based Linux system
2- Ensure KVM is available (kvm_intel loads normally)
3- Reboot the system
4- Observe dmesg output during early boot

Did you upload all of your necessary log files, screenshots, etc.?

• Yes, I've uploaded all pertinent files to this issue.
