KVM-36 compile error on Fedora 7

KVM-36 compile error on Fedora 7

[Mark Bidewell]

[-- Attachment #1.1: Type: text/plain, Size: 673 bytes --]

When building kvm-36 with the latest Fedora kernel I get the error:

kvmctl.c: In function 'kvm_run':
kvmctl.c:1046: error: 'KVM_EXIT_SET_TPR' undeclared (first use in this
function)
kvmctl.c:1046: error: (Each undeclared identifier is reported only once
kvmctl.c:1046: error: for each function it appears in.)
make[1]: *** [kvmctl.o] Error 1
make[1]: Leaving directory `/opt/kvm-36/user'
make: *** [user] Error 2

on lines:

1046                 case KVM_EXIT_SET_TPR:
1047                         break;

Commenting this lines out allows KVM to compile.  kvm-35 compiles on the
latest with no error.

Am I losing anything important by commenting them out?

Hum, the package sould be using its own headers since the local
include directory comes before the kernel's one.
Can you run "make kernel V=1" (on a clean source) and post the result?

You can workaround by adding:
#define KVM_EXIT_SET_TPR 11

Ops sorry, I misread the original message. The problematic part is the
userspace component. I can't see how it manages to include the wrong
kvm.h though.
Are you using the tar.gz package or the git tree?

Please also post the output of:

make -C user kvmctl.o

Oh, and try also:

grep -r KVM_EXIT_SET_TPR *

just in case :)

The include directory is wrong. Have you used --with-patched-kernel?

Yes I did use --with-patched-kernel.  Here is my configure command line:

./configure --with-patched-kernel --prefix=/opt/kvm

Don't. You don't have a patched kernel ;-)

Which means that you are going to use your own kernel modules. Do you
*really* want to do that?

Odd I thought fedora built the appropriate modules or does this option have
another meaning?

Historically, --with-patched-kernel was for those running a -mm
kernel, which was the only tree that contained the kvm patch.

These days it's a bit of a misnomer. It's just a question of whether
you want to use the (likely outdated) modules included in the kernel,
or build from the source package.

I'm sure you're kernel does include kvm modules. I think all Luca
meant was that the norm is to build new modules from the source
package, as they are most likely newer than those included in a
kernel.

Nevertheless, it seems that you should be able to build kvm-36
userspace on a recent kernel and use the modules you already have.

Yes.  --with-patched-kernel really means "I'm a developer using kvm.git".

Any sufficiently difficult bug is indistinguishable from a feature.
