Hello list,

I am trying to compile KVM-21 on RHEL4 U4 (kernel version is 2.6.9-42.0.10.EL SMP). While I do not have any problem compiling the 'user' and 'qemu' targets, I cannot seem to be able to build the kernel module. I would like to point out that:

1) kernel-devel packages are installed
2) the same problem happens with KVM-13/15/16/17/18/19/20
2) the same problem happens with the 2.6.9-42.0.10.EL non-SMP kernel

Here is the output I get.

I also tried older versions and found out that KVM-10/11/12/14 behave in a different (and weird) way:
they do not show any error, but they don't compile anything at all either.

Any idea what the problem is?

Thanks for the help!

Hello list,

2) the same problem happens with the 2.6.9-42.0.10.EL non-SMP kernel

There are several issues here:

- 2.6.9 appears to predate some Kbuild changes (like looking for the Kbuild file in the external module directory, and instead going for Makefile). Presumably this is easy to fix.
- RHEL 4's kernel is some mix of 2.6.9 and features from future kernels; this may defeat our compatibility detection.

This is all fixable, but will require someone with time and determination.

You might consider moving to rhel5 its got an updated 2.6.18 kernel that should be a little more compatible with kvm.
