Congratulations, it's always good to see the development moving forward! There is one thing I wonder though when it comes to PCI passthrough: Can Xen reset hardware through the d3d0 in the ACPI interface and/or through a 'bus reset' or a 'link reset'? Or can it reset hardware that is marked for passthrough only through FLR?

For details see e.g. http://www.vmware.com/files/pdf/techpaper/vsp_4_vmdirectpath_host.pdf Regards Robin.

I have a temporary build of xen-4.2.0 at http://koji.fedoraproject.org/koji/taskinfo?taskID=4493396 I would like to know a bit more about libvirt support for 4.2 before I do any proper releases as I know a lot of people use xen via libvirt.
