QEMU is a generic and open source machine emulator and virtualizer.
QEMU can be used in several different ways. The most common is for System Emulation, where it provides a virtual model of an entire machine (CPU, memory and emulated devices) to run a guest OS. In this mode the CPU may be fully emulated, or it may work with a hypervisor such as KVM or Xen to allow the guest to run directly on the host CPU.
Note that this package is produced using a Git based workflow. Please refer to README.PACKAGING before making modifications.

I'm sorry, maybe I still missing something about Obsoletes & Friends enough... Can you help me understand why qemu-kvm would be missing for all arches? In fact, I'm not only Obsoleting it, I'm also Providing it, isn't that fine?
FWIW, I've done a few tests with this repository enabled, and it seemed to work:

Furthermore, if I have the actual qemu-kvm package installed, with <= it is automatically removed, which is what I want... So things look good to me. What am I missing?
Mmm... I guess I can try with "Obsoletes: qemu-kvm < %{version}-%{release}
But, yes, the actual qemu-kvm package must be removed, because now the qemu pacakge Obsoletes it, by providing everything that it was providing before (i.e., one symlink).
I don't understand what you mean with "Doesn't the package require other packages to build or install?"
Ok, I've now tested Obsoletes: qemu-kvm < %{version}-%{release}, and no, it does not do what I want and need, while Obsoletes: qemu-kvm = %{version} does. And the SR has been accepted already, so I'm sticking to that

qemu-kvm ist missing now for all arch!
And this wrong:
Pacakges we OBSOLETE (and CONFLICT)
Obsoletes: kvm <= %{version} Obsoletes: qemu-kvm <= %{version} Obsoletes: qemu-sgabios <= 8
Should be <, not <=

qemu-kvmpackage is being installed:$ rpm -qa|grep qemu-kvm $
And:
Furthermore, if I have the actual
qemu-kvmpackage installed, with<=it is automatically removed, which is what I want... So things look good to me. What am I missing?First a short answer. An offered version (=) cannot be obsolete (<=) at the same time.
And why should qemu-kvm be removed? Doesn't the package require other packages to build or install?
