Come on, XCI sources are fully open source and available on the web!
The plain truth is that graphic card passtrough doesn't always work at
the moment, most of the problems come from the rexecution of the vga
bios (or the lack of thereof).
You can read the workaround we have in place in XCI in
tools/libxc/xc_hvm_build.c:setup_vga_pt, but even that one doesn't work
all the times.
