Thank you for the info. I searched for your name and could not find a how to.

It is important that you use the right version of guest kernel. I also downloaded mine from bb's site. I am using "kernel32-2.6.18-bb1". It was the most recent version I could find as of a month or so ago that would work with my config. Most kernels posted there would not boot with a vanilla edgy host. Try using that version. Also, it looks like you are telling the guest that /dev/sde1 corresponds to /dev/ubd0 on the command line, but that in your fstab, you are trying to mount /dev/ubda1. I would suggest using /dev/ubda in both locations. You will need to make sure the permissions and ownership are correct on your root image or /dev/sde1 depending on how you do it (and I would suggest the root image method, as that is the way I know works). A month or two ago I posted a howto on this list that you should find helpful. Look through the archives.
