Hi,
I would like to have Xen to run unmodified OS (Windows, and some other
Linuces). I know Linux may be ran Xen-aware, but the goal is to
experiment some kernel packaging, so that I need to use the distribution
kernel.
I got the FC5 isos.
I made a file "/etc/xen/fc5-guest.cfg" (see attached)
But the problem is about vifX interfaces.
Neither http://fr.gentoo-wiki.com/HOWTO_XEN#Windows_XP
nor http://gentoo-wiki.com/HOWTO_Xen_and_Gentoo tells how to bring up
such interface.
In fact I dont see anywhere any documentation on how to setup networking
for the need of Xen.
When I run Xen, I have:

	asus ~ # xm create fc5-guest.cfg
	Using config file "/etc/xen/fc5-guest.cfg".
	VNC= 3
	Error: Device 0 (vif) could not be connected. Hotplug 
	scripts	not working.

bridge-utils is already emerged.
vnc is also emerged with USE="server"

What didi I do wrong?
