Installing VirtualBox on a PAE Kernel System

I recently got stuck while trying to install Headless Virtualbox on a Centos 5.2 server per the directions at Howtoforge here. The RPM failed with the error that it couldn’t find the kernel source. I thought I had already installed kernel-devel, and confirmed that I did. The instructions were to define the KERN_DIR variable like so:

$ export KERN_DIR=/usr/src/kernels/2.6.18-92.1.22.el5-i686/
$ /etc/init.d/vboxdrv setup
Stopping VirtualBox kernel module [  OK  ]
Removing old VirtualBox netflt kernel module [  OK  ]
Removing old VirtualBox kernel module [  OK  ]
Recompiling VirtualBox kernel module [  OK  ]
Starting VirtualBox kernel module [FAILED]
(modprobe vboxdrv failed. Please use 'dmesg' to find out why)

dmesg shows this:

vboxdrv: disagrees about version of symbol struct_module

Interesting!

After several missteps, it turns out there is a separate development rpm for the PAE kernel:

$ yum install kernel-PAE-devel

After that installs, we are good:

$ export KERN_DIR=/usr/src/kernels/2.6.18-92.1.22.el5-PAE-i686/
$ /etc/init.d/vboxdrv setup
Stopping VirtualBox kernel module [  OK  ]
Removing old VirtualBox netflt kernel module [  OK  ]
Removing old VirtualBox kernel module [  OK  ]
Recompiling VirtualBox kernel module [  OK  ]
Starting VirtualBox kernel module [  OK  ]

Golden.
