Re: [Fedora-xen] [Xen-devel] [ANNOUNCE] Xen 4.2 released!
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.

Or can it reset hardware that is marked for passthrough only through FLR? It does it using whatever Linux does. Which means FLR, then for good measure also D3-D0.

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.
