/usr/bin/kvm and /usr/bin/qemu-kvm (or /usr/libexec/qemu-kvm) are the
binary that is built from qemu-kvm.git. If you want x86
virtualization you should use qemu-kvm. Some distros have called it
just "kvm" in the past.
/usr/bin/qemu is the binary that is built from qemu.git. If you want
to emulate other architectures (e.g. ARM) or run on non-x86 hosts then
you should use qemu.
