xenguest-install.py - Error Bad file descriptor in FC6 Test2 DomU and Dom0

I have a Fedora COre 6 Test 2 dom0 built from xen-3.0.2 sources. That was succssful and "xm list "worked . I did not build a domU kernel though.

I am trying to install FC6 Test2 as guest Os. I setup an http server in the same machine to grab the images of Fc6 TEst2 from a directory.

When I did xenguest-install.py, I get this error. Please let me know what am I missing here. 
1. Have I not setup my disks correctly ?
2. Is my http daemon configuration causing problems ?


Starting install...
