+> Upstream QEMU is capable of emulating many different platforms (arm,
+> i386, m68k, mips, ppc, sparc, x86_64, etc). On the other hand, you have
+> qemu-kvm, which is qemu (i386 and x86_64 architecture support only) with
+> KVM (kernel-based virtual machine) additions, allowing you to run
+> virtual machines at close to native speed. qemu-kvm is the version you
+> want if you have a CPU that supports hardware virtualization and you
+> only need to run virtual machines for the i386 and x86_64 architectures
+> (Linux, Windows, BSD, etc).
+> 
+> Not all processors support KVM. You will need an x86-based machine
+> running a recent ( >= 2.6.22 ) Linux kernel on an Intel processor with
+> VT-x (virtualization technology) extensions or an AMD processor with SVM
+> (Secure Virtual Machine) extensions (also called AMD-V). Xen has a
+> complete list of compatible processors. For Intel processors, see also
+> the Intel® Virtualization Technology List.

+ You should also contact pterjan wo was maintainer for a long time
