[fedora-virt] qemu versus qemu-kvm?



  just so i understand the distinction, the qemu-system-x86 package
comes with both executables /usr/bin/{qemu,qemu-kvm}.  as i read it,
the "qemu" executable is the original, non-KVM version which still
works but only in terms of full software emulation (as it always has),
while qemu-kvm is the fork of qemu that adds KVM functionality, is
that correct?

  and if that's correct, what happens if qemu-kvm is invoked but
recognizes that there is no HW virt assist?  does it fall back to
invoking qemu?  or does it contain the full qemu functionality so it
had no need to ever use qemu?

  put another way, if i want to run virtualization on a system that
has HW virt assist, do i have any need to hang onto the "qemu"
executable for any reason?
