This is what I get when I try to start a VM:

        VirtualBox can't operate in VMX root mode. Please disable the
        KVM kernel extension, recompile your kernel and reboot
        (VERR_VMX_IN_VMX_ROOT_MODE).

Whereupon I do:

        sudo modprobe -r kvm_intel
        
and everything works (no kernel recompile or reboot necessary).
