Hi!

I tried to compile kvm-16 on Kubuntu Edgy - so far unsuccessfully. The configure succeeds but the make process fails with the following output:

Hi!
I tried to compile kvm-16 on Kubuntu Edgy - so far unsuccessfully. The configure succeeds but the make process fails with the following output:

[snip]

Quoted 1 line

make[2]: Entering directory `/usr/src/linux-headers-2.6.17-11-generic'

That's a very old version of the kernel, compared to the age of kvm. I think 2.6.19 is a good minimum version for building the kvm modules.
Can you try again after updating your kernel sources?

I tried that but it didn't work. However, in the meantime I installed a new kernel and got kvm to work (see other post).

Cheers,

Sorry! I just answered the wrong post. OK, I updated my kernel to 2.6.20.3 and managed to compile kvm. Btw I used kvm-12 as indicated here:

http://kvm.qumranet.com/kvmwiki/Downloads

Is this the latest version to work with a 2.6.20 kernel?

Thanks for your help.

Cheers,

Martin

No, that's the version included in 2.6.20. The updated kernel module kvm-16 builds perfectly with a 2.6.20 kernel.

configure should compile the module as long as you don't specify --with-patched-kernel.

Ok, that's a misstatement. configure wouldn't compile the module, just set the makefiles to do so.

A couple of lines above the first error reported there is a LINUX_VERSION_CODE check. There is a similar one surrounding kvmfs_get_sb() in external-module-compat.h. Can you change both from 16 to 17 and report?

The definition of struct file_system_type.get_sb for 2.6.17 is:

struct super_block *(*get_sb) (struct file_system_type *, int,
const char *, void *);

So a slightly modified kvmfs_get_sb() is needed. I'm not sure how to cope with this though since this #if guard isn't in external-module-compat.h. I was under the impression that per-kernel version defined were frowned upon in mainline code.

What's the correct solution to this?

See the 'sync' target in kernel/Makefile. It looks like all that is necessary is to add the 2.6.17 case to external-module-compat.h.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
