Hi Maintainer

I added 64bit pci hotplug support to hvm guest recently.
Then I found XudongHao had ever sent a similar patch, but it wasn't
merged in qemu-xen-traditional.

http://lists.xen.org/archives/html/xen-devel/2012-08/msg01168.html

I am interested in the result about that patch.

thanks
zduan

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 ?

Ian.

That is not the case: the patch is against qemu-xen-traditional
(hw/pass-through.c doesn't exist on QEMU upstream based trees).

Ah, I was tricked by the subject line which says qemu-xen!

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

Ian Jackson, could you please weight in on this discussion?
