Re: [Xen-devel] [PATCH 2/2 v2] graphics passthrough with VT-d

Thanks for this.  However:

 * It breaks the build if passthrough is disabled (eg due to lack
   of pciutils-dev).

 * Reindenting all of the code in pc.c which initalises out the
   various graphics cards is very merge-unfriendly.  Is that change
   needed at all, or could you just disable the various graphics cards
   on the qemu command line ?

 * Likewise, in vl.c.

Regards,
Ian.
