- Convert qemu-kvm from a script to a symlink. This method of
  invoking the QEMU emulator has been deprecated for some time,
  but is still provided. It has as it's origins a version of QEMU
  which had KVM acceleration enabled by default. In it's recent
  incarnation it is a script which adds '-machine accel=kvm' to the
  beginning of the list of command line options passed to the
  emulator. This method collides with the now preferred method of
  specifying acceleration options by using -accel. qemu-kvm is now
  changed to simply be a symlink to the same QEMU binary which the
  prior script exec'd. This new approach takes advantage of a built
  in QEMU feature where if QEMU is invoked using a program name
  ending in 'kvm', KVM emulation is enabled. This approach is
  better in that it is more compatible with any other command line
  option that may be added for specifying acceleration (not that
  you should do that).
  For those who have taken advantage of the fact that you can add
  additional command line options to the qemu-kvm script, or doing
  other things in that script you will just need to create an
  alternate script "emulator" to achieve the same. It's possible
  that there may be some very subtle behavioral difference in the
  switch from a script to a symlink, but given that qemu-kvm is a
  deprecated package, we're not going to worry about that.
