I recently did a complete reinstall of Fedora from 10 to 14. In Fedora 10 I had no problem installing Virtual Box.Under Fedora 14 I cant start up VB and I get this message when I try to use DKMS :

Stopping VirtualBox kernel modules [ OK ]
Uninstalling old VirtualBox DKMS kernel modules [ OK ]
Trying to register the VirtualBox kernel modules using DKMS
Error! Your kernel source for kernel 2.6.35.14-106.fc14.i686.PAE cannot be found at

I am extremely new to Linux and computers somewhat, so simple explanations would help me out the most. Thanks

you are aware that fedora 14 is past it's End Of Life ( EOL date 2011-12-08 )
it is not support any longer

please stay current and install fedora 16 and in about 2 to 3 months install fedora 17

install the source
also if this IS a 32 bit HARDWARE with 4 gig ram then use the PAE
but
if it IS a 64 bit computer like an i5 or i7 then install the 64 bit Fedora 16
AND the kernel source

Thanks for the reply. Yes, I am aware that Fedora 14 is past its EOL, however I like the look and feel of it and I have tried 16 which constantly crashes on me. I figured out the issues shortly after posting, so problem solved. Thanks again
