compiler problem in Read Hat ES 4

Hi,
we are trying to kmstall kvm on a Read Hat Enterprise 4 with all the latest updates, and when we do the "make" we
get this error

The gcc version is 3.4.6; I have read that there were problems with older gcc versions. Is this another bug?

Hi,

It seems like a gcc32 problem.
Please try to use your default gcc (3.4.6) to compile qemu instead of gcc32 Just type in <kvm-dir> "configure --qemu-cc=gcc"

Hope that helps,
Uri.

Hi Uri,
it has compiled OK with gcc, but it has not produced any module ( .ko) It seems like does not do anything when the "make" should do this part:

Hi Frank,

The modules were probably already made.
Try to remake (from <kvm-dir>): "make clean ; ./configure --qemu-cc=gcc ; make"

Uri.

Hi Frank,

It seems it would be easier if you'd build kvm on a more recent linux kernel (version 2.6.16 or later).
You could not make the kvm modules because 2.6.9 kernel does not use Kbuild, but expects that information to be in the Makefile. So... I typed "cd kernel; mv Makefile Makefile.orig; cat Kbuild Makefile.orig > Makefile; make".
That started building the modules, but include file <linux/mutex.h> was not found.
linux/mutex.h was introduced in version 2.6.16

If you insist on 2.6.9, try to replace the mutex with a semaphore (kvm_main.c and kvm.h).

Uri.

It wouldn't be ES 4 then. The way the enterprise releases work is that no software is upgraded, therefore you don't find new and exciting changes in the way things work. Instead, any bug fixes or security patches are backported to the original software.

ES is intended to provide extremely stable platforms for production servers, which normally doesn't make it a good candidate for building new kernel modules.

I assume that's why ES is being used.

I was merely pointing out the cause of the problem, and offering a couple of ways for solving it.
Of course, there may be other solutions.
A valid alternative, which I did not mention due to a possibly long waiting time, is to wait for KVM (and/or a newer Linux kernel version) to be included in a Red Hat ES release or update.

Regards,
Uri.

Hi Uri,
I have install 2.6.19.2 kernel in Red Hat and I have got .ko files at last !!
But it seems if there is a problem when I try to load the module:

modprobe kvm-intel
FATAL: Error inserting kvm_intel (/lib/modules/2.6.19.2/extra/kvm-intel.ko): Operation not supported

I have tried to load "kvm" one (without intel extension) but I suppose it is not right becase qemu fails:

/usr/local/kvm/bin/qemu -hda vdisk.img -cdrom /var/tmp/ubuntu-6.10-server-i386.iso -boot d -m 384 open /dev/kvm: No such file or directory Could not initialize KVM, will disable KVM support

I need your help again.
Thanks a lot.

Frank

Hi!

Please check the output of dmesg. This usually means that a) kvm isn't supported or b) it's disabled by the BIOS.

Thank's. You were absolutely right. Virtualization was disbled. I enabled it and module seems to load.
The only thing is that I get this message:

kvm: no version for "struct_module" found: kernel tainted.
kvm: msrs: 2

does it mean any trouble?

Hi!

Usually not. It may be impossible to get support from Red Hat if the kernel is tainted (depending on their policy). The second line is just a debugging aid.
