Hello team, aside from this issue we'll be facing with 6.2 also this issue. VirtualBox 7.1.4 has support for Kernel 6.12 but you have to include a parameter to the kernel command line in the bootup or VirtualBox will not start. kvm.enable_virt_at_load=0 I added it to /etc/default/grub I got this from Linux Magazine January 2025 issue.
