+lsmod|grep kvm
+kvm_amd                55516  0
+kvm                   413942  1 kvm_amd

+Whether it's loaded or not doesn't seem to make any difference.
+
+If I add the -enable-kvm option, it fails with ...
+KVM not supported for this target
+No accelerator found!
+
+Checking under htop shows it's clearly cpu bound, using 2 of my 4 cores.
+
+The command I used to run qemu was ...
+qemu-system-x86_64 -cdrom "$Iso" -hda mageia"$Arch".qcow2 -boot d -net nic
+-net user,net=192.168.10.0/16,host=192.168.10.3 -m 4096 -vga qxl
+with the Iso and Arch variables set appropriately.
+
+Suggestions for faster disk/network options?
+
+Given that other people do find it useful, it's obvious there's something
+wrong either with the options I'm using (or not using), or my hardware or
+bios settings.
+
+Hopefully it's not the hardware. The cpu is an AMD FX(tm)-4170 Quad-Core
+Processor, with the following flags shown in /proc/cpuinfo ...
