I'm kind of new to all of these and am sort of feeling my way.  It seems 
I was putting a default CentOS install which contains a /boot partition 
and another LVM partition inside an LVM on the host.  I don't know if 
that's good or bad, but for now I am installing all guests as a single 
root partition inside the host LVM and can mount them like so:

lomount -t ext3 -diskimage /dev/VolGroup00/vg_name -partition 
1 /mnt/image

Thanks for the responses.
