Thanks for the reminder.... in fact I posted a qemu patch in February http://lists.gnu.org/archive/html/qemu-devel/2014-02/msg00319.html I thought it was applied, but it's not yet in trunk.... I used to use a patched qemu, but when I upgraded to 2.0 I forgot about this patch. I am going to re-check with a patched qemu, and ping them.
