[virt-tools-list] Emulating raspberry pi (arm1136-r2) in virt-manager?

This is looking a bit more complicated than I thought... I now
understand that I can't simply define the ARM machine in xml and define
it using virsh, as the CPU type (arm1136-r2) is rejected by libvirt
which can't test if it's valid or not.
So I think what Cole and Martin are suggesting is that I define a dummy
emulator (the wrapper script) which plays with the arguments passed by
libvirt and then calls the real emulator qemu-system-arm. I had a quick
go at this but I couldn't work out where to put the wrapper script. I
tried putting a wrapper (qemu-system-pi - written in python) in
/usr/bin, but virsh define couldn't find it.
I also get the impression that libvirt calls the wrapper during define,
to validate the arguments? So these calls also have to be caught and
passed to the real emulator.
Overall I am tempted to stick with my original method of simply issuing
the qemu-system-arm command directly from a script, but if anyone can
suggest how I can get the wrapper to be found - or point me to an
example of one - then I will keep trying. Thanks for all the help and
encouragement so far.
