I need to create an http url at my laptop to have a Ubuntu installation begin within my laptop on a Xen environment. This is how the final thing will look like.

The host and client are both going to be my laptop, I Googled and came across apt-mirror and some other packages. I do not want to archive entire 15 GB Ubuntu repositories on my machine.

It is not possible to use a CD,ISO,loop mounted disk (reason mentioned below). I have tried using netboot image on local machine which failed because if you are attempting to create a virtual machine on a hardware which does not support VT virt-manager installer necessarily needs a URL of this sort

http://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-i386/current/images/netboot/

Any other option to create guest OS is simply grayed out.

The unfortunate part is my Ethernet connections do not work when I boot with Xen-4.0 and a pv-ops Dom0 kernel from Jeremy's tree. Which is where I have to do this work. So I have to create a URL structure which is similar to Ubuntu mirrors. So how can I do this in bare minimum so that at least the console boots and once the console comes I can do some work.
