Thread-topic: With latest Qemu and Xen-3.4, VT-d does not work
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,
