qemu-system on debian derivative OS is a meta-package which installs qemu-system-* for all architecures understood by qemu. This is different from redhat type OS where the qemu-kvm package installed with dnf only installs the qemu-system-* binary matching the host architecture. This gives two problems, first there is inconsistency in openstack-ansible deployments between redhat and debian OS. Second, there is a potentially unexpected emulation of architectures when launching VM on a cloud with a mix of compute architectures when a full set of qemu-system-* binaries is available on a compute node. The compute node becomes a candidate for scheduling any of the supported architectures and a very specific configuration is needed both from the operator and end user to ensure that VM are run on a native architecture or emulated as required. This patch changes the installation so that redhat and debian compute nodes only have the native qemu-system binary installed. A new feature should be introduced to openstack-ansible in the future to explicitly control installation of non-native qemu-system-* binaries and write the config options for controlling emulation.
