The 6.12 kernel has changed the way virtualisation modules are loaded. Some discussion, with workarounds, here: https://www.virtualbox.org/ticket/22248 https://lore.kernel.org/kvm/ZwQjUSOle6sWARsr@xxxxxxxxxx/T/ I was able to get VirtualBox to start by unloading the kvm_intel module with the command: rmmod kvm_intel The above links also have a kernel command line fix which I haven't tried. (I only use VirtualBox occasionally, to run a Windows XP VM which I've never managed to get working with KVM. Otherwise I prefer Virtual Machine Manager.)
