TL; DR: A versão do kernel em execução era mais antiga que a origem do kernel que o VirtualBox encontrou ao tentar instalar. Não há necessidade de construir a fonte por conta própria; A resolução final foi remover a versão mais recente do kernel e instalar a versão correspondente encontrada em uname -r , em todo yum .
História:
Ao tentar instalar o VirtualBox-4.2 em um novo servidor CentOS, recebi o seguinte:
Your kernel headers for kernel 2.6.32-358.6.2.el6.x86_64 cannot be found at
/lib/modules/2.6.32-358.6.2.el6.x86_64/build or /lib/modules/2.6.32-358.6.2.el6.x86_64/source.
Então, seguindo as instruções do CentOS Eu preciso da fonte do Kernel eu tentei pegar a fonte e eu agora tem ~/rpmbuild/SOURCES/kernel-2.6.32-358.6.2.el6 com 2 pastas: linux-x e vanilla-x .
Eu tentei instalar o VirtualBox novamente, mas ele errou sobre não encontrar a fonte do kernel, então eu também tive que configurar estes symlinks:
/lib/modules/2.6.32-358.6.2.el6.x86_64/build -> /usr/src/kernels/2.6.32-358.6.2.el6.x86_64
/usr/src/kernels/2.6.32-358.6.2.el6.x86_64 -> /home/dirt/rpmbuild/BUILD/kernel-2.6.32-358.6.2.el6/vanilla-2.6.32-358.6.2.el6
Mas ao tentar instalar o VirtualBox agora recebo erros sobre a necessidade de executar o make:
/var/log/vbox-install.log
