Comment # 12 on bug 1222186 from Larry Rainey

The issue is wrong major minor numbers

the should be
crw-rw---- 1 root vboxusers 10, 122 Apr  1 08:24 /dev/vboxdrv
crw-rw-rw- 1 root root      10, 121 Apr  1 08:24 /dev/vboxdrvu
crw-rw---- 1 root vboxusers 10, 120 Apr  1 08:24 /dev/vboxnetctl

they are

crw-rw---- 1 root vboxusers 10, 120 Apr  1 07:27 /dev/vboxdrv
crw-rw---- 1 root vboxusers 10, 119 Apr  1 07:27 /dev/vboxdrvu
crw-rw---- 1 root vboxusers 10, 118 Apr  1 07:27 /dev/vboxnetctl

I have a good fix - need others to validate it.

sudo /usr/lib/virtualbox/vboxdrv.sh start will fix it without a reboot with
this file

too big to paste here so here is a link put it in /usr/lib/virtualbox/
