The intention would be a direct, non-interactive, installation from a PXE
server.  No preinstalled image exists on the allocated drive.  Or maybe
I'm misunderstanding your suggestion ...

I would assume that the hypervisor would need to proxy the PXE
installation for the GuestOS domain?  Are you suggesting that the image
pulled down by the initial first stage of the PXE tftpboot be a
modified Xen kernel?

Indeed ... can I assume from the reply that this hasn't been looked at
by anyone as yet?

Thanks Brian
