Hi, list,
I just tried Xen-3.4 with latest QEMU, but it seems that VT-d does not
work properly. Devices could be hidden through PCIBACK, but could not be
assigned to guest (Linux guest cannot see the device through 'lspci'). VT-d
works well with Xen-3.4 and its corresponding QEMU, also it works well with
latest Xen upstream and latest QEMU.
Best Regards,
-- Dongxiao
