QEMU is the core project which provides the userspace emulation, that is
used in conjunction with KVM hardware acceleration from the kernel.

Originally (many years ago now), KVM relied on a fork of the QEMU codebase,
which operating system vendors often packaged up as a binary called
'qemu-kvm' or 'kvm'.

These days, all KVM support is directly integrated in normal QEMU binaries.
So Best practice is to just use the "qemu-system-$ARCH" binaries for KVM
support directly. Any 'qemu-kvm' or 'kvm' binaries that you still see in
any OS distros are merely there for back compat.

Daniel
