Stefano is not the maintainer of this tree, Ian Jackson is. On the other hand the patch you link to is against qemu-xen, which Stefano does maintain, so I'm a bit confused. Perhaps you should also have CCd Xudong? I've done that too. This may also relate to http://bugs.xenproject.org/xen/bug/28 ?

That is not the case: the patch is against qemu-xen-traditional (hw/pass-through.c doesn't exist on QEMU upstream based trees). > Perhaps you should also have CCd Xudong?

So anyone knows if it could be accepted? I think it could be used to fix an oracle internal bug. We found when we hotplug many pci vf to a hvm, some regions may need to be mapped above 4G. That patch add the support. thanks zduan > Ah, I was tricked by the subject line which says qemu-xen! > >>> Perhaps you should also have CCd Xudong?
