Install VBox on Centos - Kernel Header problem

[leo476]

Hi,
i'm trying to install virtual box on my centos 5.2 system. I did the following:

• updgrade kernel
  install kernel-devel, headers

current version:

• kernel-2.6.18-371.1.2.el5
  kernel-devel-2.6.18-371.1.2.el5
  kernel-headers-2.6.18-371.1.2.el5

When i'm trying to compile the vb kernel via: "service vboxdrv setup"
I get the following error:

Your kernel headers for kernel 2.6.39.3 cannot be found at
/lib/modules/2.6.39.3/build or /lib/modules/2.6.39.3/source.

Why is VB searchig for that version of the kernel? I took care that i have the same version of kernel header and kernel itself but it is still not possible to compile.

Any ideas?

Thanks

What does running uname -r in a terminal return?

[leo476]

it returns: 2.6.39.3

That's why im confused. I also tried to install header and devel source for this version but it seems that there is no package available.

Did you reboot after the update and made sure to start with the new kernel?

[leo476]

when i'm trying to reboot, i get a kernel panic...

is it because the new kernel is not compatible to Centos 5.2? (same when i just do a "yum update" the result is a kernel panic and i'm not able to boot the system any longer).

Now i have reinstalled the whole system. The current kernel version is by typing 'uname -r':

2.6.39.3

By typing 'rpm -qa kernel' i get:

kernel-2.6.18-164.10.1.el5
kernel-2.6.18-164.15.1.el5
kernel-2.6.18-164.el5
kernel-2.6.18-164.11.1.el5
kernel-2.6.18-308.1.1.el5

By typing: "rpm -qa kernel |sort |tail -n 1" i'll get: kernel-2.6.18-308.1.1.el5

Can you help me to understand the difference between 'rpm -qa kernel' and 'uname -r'?

If i would update now the kernel via 'yum update kernel' i will get the following kernel version: kernel-2.6.18-371.1.2.el5 by typing in 'rpm -qa kernel'.

And if i would like to install the correct kernel-devel by

"yum install kernel-devel-$(uname -r)"

i'll get the following:

No package kernel-devel-2.6.39.3 available.

These questions would be better answered by the CentOS folks.
