[Xen-users] My GPU won't pass through. Is this my goodbye to Xen?

[Folatt <folatt@xxxxxxxxxxxx>]

My plan was to use Xen in order to have a software program I could play 
with without having to worry that it could crash the OS. I could always 
build a new one.
However this requires eclipse and thus Xorg.

Since I'm on a tight budget and like my computers silent and low-powered 
I have a AMD APU and thus my graphics "card" consists of a [AMD/ATI] 
Kabini [Radeon HD 8400 / R3 Series].
So Xorg can't find a graphics driver and thus can't run unless I VGA 
passthrough my GPU.
Trying to do a VGA passthrough with "sudo xl pci-assignable-add 00:01.0 
&& sudo xl create -c etc/xen/ArkOS-Dev_PV.cfg" and then "sudo 
pci-assingnable-remove -r 00:01.0" results into seeing my configuration 
do a Segmentation fault and core dump.
Is this the end of my Xen endavour?

If so, goodbye Xen Project. it was nice knowing you. Setting you up took 
me weeks, but I have gotten wiser out of it.
I almost had you working, but at the last step you budged.
Until I can gather some money for a new motherboard, goodbye.
