The character device /dev/vboxdrv does not exist in hardy/gutsy latest kernels

locate vboxdrv.ko

dpkg -L virtualbox-ose-modules-2.6.24-18-generic

(may need to locate -u first)

then I did

insmod /path/to/exact-same-kernel.../vboxdrv.ko

sudo insmod /lib/modules/2.6.24-18-generic/misc/vboxdrv.ko

lsmod | grep vbox

/etc/init.d/vboxdrv status
