Hi thanks for the response.  You have misunderstood me so let me 
clarify.   Here in this case the volume wheezytest-root does not have 
any data yet and this is why I am trying to pygrub boot the installation 
ISO so I can then perform the installation.  So I would want the ISO 
first in this case.
There is claim that this can be done this way (instead of direct booting 
a copy of the kernel and initrd) but my guess is that either my pygrub 
is too old or maybe the wheezy Alpha1 installer is missing some 
important bits?  I can't be sure because that Error is cryptic and based 
on my searches can happen for different reasons.  What really has me 
miffed though is that my manual pygrub test output looks like it did 
find and extract the kernel and initrd.
