Adjust system for use of qemu with kqemu:
Make sure you have all you need:
-# apt-get update ; apt-get install qemu grml-kerneladdons
+# apt-get update ; apt-get install qemu grml-kerneladdons-$KERNELVERSION
Then set up kqemu:

--
+Use KVM (Kernel-based Virtual Machine for Linux):
+
+Make sure to install the relevant tools:
+# apt-get update ; apt-get install kvm
+# modprobe kvm
+
+Test it with a minimal system like ttylinux:
+# wget http://www.minimalinux.org/ttylinux/packages/bootcd-i386-5.3.iso.gz
+# gzip -d bootcd-i386-5.3.iso.gz
+# kvm -cdrom bootcd-i386-5.3.iso
