Bug 1085074

Description of problem:

On the VNC view I see:
Fatal IO error 0 (Success) on X server:1 

Version-Release number of selected component (if applicable):

Downloaded from:
https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/x86_64/os/LiveOS/

Which shows todays date.


How reproducible:
100%



Steps to Reproduce:

1) Boot Fedora with Xen.
2) Download the 'vmlinuz' and 'initrd.img' image. 
3) Create this file (say test.cfg)
extra="root=live:http://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/x86_64/os/LiveOS/squashfs.img  repo=http://dl.fedorapr
oject.org/pub/fedora/linux/development/rawhide/x86_64/os"
kernel="vmlinuz"
ramdisk="initrd.img"
memory=1024
maxmem=2048
maxvcpus = 2
vcpus = 2
name = "rawhide-64"
vif = [ 'mac=00:0f:4b:01:00:87,bridge=switch' ]
disk= ['phy:/dev/guests/rawhide-64,hda,w']
vfb = [ 'vnc=1, vnclisten=0.0.0.0,vncunused=1']

4). Setup a bridge (in this case called 'switch').

5). xl create -c test.cfg

Actual results:
If I try to start 'Xorg' in the console I get:
