In VirtualBox Gentoo wiki is written that, to run VirtualBox, one should emerge app-emulation/virtualbox-modules and load them into memory either by using modprobe or by adding the following line modules="vboxdrv vboxnetadp vboxnetflt vboxpci" into /etc/conf.d/modules
I did nothing of mentioned above (except for emerging virtualbox-modules, of course) but nevertheless lsmod shows that all virtualbox-modules are loaded just after the boot (without even asking me if I need them): $ lsmod Module Size Used by vboxpci 12846 0 vboxnetadp 18502 0 vboxnetflt 17028 0 vboxdrv 361873 3 vboxnetadp,vboxnetflt,vboxpci kvm_amd 2159235 0 kvm 480742 1 kvm_amd irqbypass 2808 1 kvm Can anybody explain me who loads virtualbox-modules without my consent and how I can make them loaded only when I need them (just before I am going to run VirtualBox, which I do not so often)?
