FC5 xen guest installation

[bibiandco]

I tried the FC5 xen guest installation, explained in http://www.fedoraproject.org/wiki/FedoraXenQuickstartFC5, and it worked perfectly, but...

I use LVM on my xen0, and I don't want my xenU to use LVM inside the xen0 volume... which is what happen whith the ANACONDA installation...

What is the procedure to install a FC5 guest directly on existing volumes ?

Is there a documentation for Pygrub ?

Thanks
