 When I run this command:

  -hda /vm/RIPLinux-11.7-non-X.iso
  -smp 4,maxcpus=4,cores=4
 I get this error:
 
   No SMP KVM support, use '-smp 1'

qemu-system-x86_64 comes from qemu-system package, not from
qemu-kvm package.  KVM features, including SMP, are developed
in qemu-kvm first and ported to qemu later when they're mature
enough.  So no doubt qemu does not have smp support, -- quite
some changes (for 0.12) are required for qemu to support SMP,
in this area qemu-kvm and qemu are significantly different.

 I think that you are trying to be too smart with this
 package. You are modifying and extending the qemu package
 unnecessarily. It works fine out of the box. Please

If it worked out of the box, why you file a bugreport?
That's one of the examples where it does not work out
of the box, and there are many other examples.

 consider releasing a new package based on qemu-0.14.0
 without all of the value-added stuff.

Which value-added stuff?  I'm afraid you don't understand
what you're talking about.

Thanks!
