Answer 2

$ cat /var/log/vboxadd-install.log
/tmp/vbox.0/Makefile.include.header:97: *** Error: unable to find the \
sources of your current Linux kernel. \
Specify KERN_DIR=<directory> and run Make again.  Stop.

Seu arquivo install.log é muito claro: você precisa instalar os cabeçalhos,

sudo yum update
sudo yum install kernel-headers kernel-devel

e, em seguida, você pode reinstalar o VirtualBox.
