Mirek - since you set ITM and bugs w/ ITM should have an owner, assigning to you.

Hi Murilo,
Thanks for reporting this bug. Actually *qemu 7.0* is not supported on ppc64le(RHEL). Per Mirek, "C9S allow some of custom usage of CentOS 9 Stream". I will help to reproduce it.
Thanks.

Steps to reproduce,
1. git clone https://gitlab.com/redhat/centos-stream/src/qemu-kvm.git
2. ./configure
3. #clang -m64 -mlittle-endian ... ./target/ppc/cpu-models.c
./target/ppc/cpu-models.c:22:10: fatal error: 'qemu/osdep.h' file not found
#include "qemu/osdep.h"
         ^~~~~~~~~~~~~~
1 error generated.
...

QE realized it need many libraries to compile the final build, but my host is not a build server. In the code, it missed something was like" #if defined..." in cpu-models.c at the following lines.
-------------------------------------------------------------
798                                                          --missed
799     /* PowerPC MPC603 microcontrollers */
800     { "mpc8240", "603" }.
...

...
904     { "apollo7pm", "7457a_v1.0" },
905 #endif

Hi David and Laurent,

Is it enough for QE to verify the bug ? Can you guys help to tell it if you prefer to use other ways? 

Thanks

This is not the expected error.

In the centos-stream repo, you can use the following command to install the missing package:

  git clone https://gitlab.com/redhat/centos-stream/src/qemu-kvm.git
  cd qemu-kvm
  git checkout qemu-kvm-7.0.0-1.el9

  make -C .distro rh-env-prep

Then you can build locally the package with:

  patch -p1
diff --git a/.distro/qemu-kvm.spec b/.distro/qemu-kvm.spec
index 38d4980d12..d654c578e0 100644
