Looks like I didn't get it then!

I have made three lvm partitions and in the first
VolGroup0 Dom0 ubuntu is sitting. In VolGroup2
I am trying to install CentOS5.2.

What is that I have to do in Dom0 to import the
partitions made in Dom0 (vi xen-create-image) so 
that they are visible in DomU. 

Or, is this done in DomU setup and if so, at what
point do I do this during the DomU setup?

Appreciate if you could point me to some URL/
documentation that I could read and catch up.
