[Xen-users] Backend device not found!!.

["Lamia M.Youseff" <lyouseff@xxxxxxxxxxx>]

Hi All,
I am having a really hard time starting xen-domain with a vbd file. I 
always get the error
"Error: Device 0 (vif) could not be connected. Backend device not found."
I have been using xen 2.0 before, but now i am not able to start domains 
with xen 3.
I have no clue what could be the problem. I have done some testing, 
which is shown in the log below.
Any ideas/ help will be very appreciated,
