Linux Mandriva ONE 2009 Virtual Box 3 error?
Hi, im having a problem with MAndriva Linux 2009. Installed perfect, but i want to use Windows inside MAndriva so i used the Sun VirtualBox program. It installed and now i try to start a virtual HD that i made with it and i get Kernal Driver Not installed or somthing like that (error 1908) so i do as is says, open terminal as root and exicute command but it endsup failing. So i go to the log and i read:

Error! Your kernel source for kernel cannot be found at
/lib/modules/… or /lib/modules/…
You can use the –kernelsourcedir option to tell DKMS where it’s located.
Failed to install using DKMS, attempting to install without
/usr/share/virtualbox/src/vboxdrv/buil… line 100: make: command not found

please help!
