The kernel itself and all other modules might be installed, just some custom modules perhaps failed to build. I build 4.9-rt1 without issues and had also good luck with DKMS. It was able to build vbox modules. $ ls -hAl /lib/modules/4.9.0-rt1-1-rt-presonus/kernel/misc/ total 688K -rw-r--r-- 1 root root 582K Dec 24 08:14 vboxdrv.ko -rw-r--r-- 1 root root 16K Dec 24 08:14 vboxnetadp.ko -rw-r--r-- 1 root root 41K Dec 24 08:14 vboxnetflt.ko -rw-r--r-- 1 root root 39K Dec 24 08:14 vboxpci.ko However, sometimes DKMS can't build those modules, but then the kernel still could be used, just vbox doesn't work with this kernel. In your case, KMS is something graphics related and you seemingly use VMware. Again, perhaps a linux-header package wasn't installed and after installing the linux package DMKS was missing headers.
