I have tested with the Live version of Fedora 17 and Fedora 18 LXDE. With F17 it failed starting but with F18 it worked fine.
According to comment #1, the system booted all the way to your rootfs and then started failing in various virtualbox related services. Notably: [ 18.746904] mount[551]: mount: unknown filesystem type 'usbfs' [ 18.749171] systemd[1]: vbusbf.mount mount process exited, code=exited status=32 fails with a 3.6 kernel because usbfs was removed in the 3.5 kernel release. You'll probably need to update your various vbox/dkms things. Fedora doesn't provide vbox and there is nothing that indicates this is an actual kernel problem.
Thanks for the response, I fixed it editing the file /etc/fstab and commenting out the line none /vbusbf usbfs rw.devgid=501,devmode=664 0 0 (In reply to comment #6) > According to comment #1, the system booted all the way to your rootfs and > then started failing in various virtualbox related services. > > Notably: > > [ 18.746904] mount[551]: mount: unknown filesystem type 'usbfs' > [ 18.749171] systemd[1]: vbusbf.mount mount process exited, code=exited > status=32 > > fails with a 3.6 kernel because usbfs was removed in the 3.5 kernel release. > You'll probably need to update your various vbox/dkms things. > > Fedora doesn't provide vbox and there is nothing that indicates this is an > actual kernel problem.
