You posted in "Linux Hosts", but your is host is in fact Windows 10. The host is who provides the accommodation, the guest is who uses it. Topic moved to "Windows Hosts".

You have Hyper-v enabled.

See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

I had the same Kernel Panic error while trying to install RHEL 9 on my Windows 11 Home Edition host using the latest version of VirtualBox as of this morning. I discovered that the Hyper-V features were causing the problem. I had to go into the Windows Features and uncheck "Virtual Machine Platform" and "Windows Hypervisor Platform" in order to avoid the Kernel Panic. I hope this helps you.

BLadley, thanks for helping! Turning things off in Windows Features doesn't always kill off Hyper-V. The link in Mpack's post has amore thorough method.
