Actually not quite correct. Historically '/usr/bin/qemu-kvm' is provided
by whichever 'qemu-system-$ARCH'  RPM matches your name arch. With recent
modularization, its now provided by 'qemu-system-$ARCH-core'. So everyone
will have qemu-kvm if they've installed the sub-RPM matching their host
arch.

The 'qemu-kvm' RPM is just an empty RPM that depends on whichever
'qemu-system-$ARCH' matches your host, and thus provides '/usr/bin/qemu-kvm'
This is just convenience to let downstream app RPMs depend on qemu-kvm
instead of a big set of per-arch conditionals.
