Xen users - Jan 2012 - Can someone offer hints on how to take a xen domu based on redhat and make it a aws/ec2 instance?

I have a domu based on redhat running locally on a centos dom0.  This domu has a
secondary virtual drive mounted inside it.  It is made up of three LV''s
- /, /usr/store, swap.

As preparation, and ''cause I am not sure how AWS handles the kernel and
initrd, I made sure to copy the kernel and initrd I use to the /boot in the lv
that houses /.  I also made sure that the ethernet interface has dhcp rather
than a static address.

It gets more complicated, the domu is designed to allow rlogin access for admins
rather than ssh (ssh takes you to the app admin interface.)  I suppose I can
open the appropriate firewall hole using the aws security interface.

I know how to create an aws instance from a public or even private aws ec2 image
already on amazon (and how to create an image from a running instance.)  The
questionsI have is how do I take these 2 (or 3) local LV''s and produce
an image suitable for uploading to amazon to run there?  How do I then upload
the image(s) and run them?

Thanks - Yossie
