Ok, I have it all running properly now.  Unfortunately there is an issue
with aufs+v2.6.30 such that I could not use a live-cd image, so I had to
use a vmware image for now.  I am working with the susestudio devs to
find a solution to the live-cd problem, as I think it is a more ideal
format.

But anyway, here is a link to the vmware appliance:

ftp://ftp.novell.com/dev/ghaskins/LTTng_demo.x86_64-0.143.1.vmx.tar.gz

It can probably work with other VMMs, but I haven't tried this (for
instance, I think studio testdrive is Xen based).  Its a little big at
729MB.  I will work on getting this smaller (I think ~350MB is
attainable).  When it runs, it will auto-login the user and pop up the
attached PDF to walk the user through how to use it.  Please give it a
whirl and let me know what you think.

Regards,
-Greg
