Subject: [Xen-devel] Re: graphics passthrough with VT-d

FYI, apparently I passed through the wrong usb bus, now with all USB 
controllers passed through I have keyboard and mouse in HVM domU.
Knoppix still boots on secondary gfx cards (and even uses Compiz Fusion 
on 3D accelerated desktop), but I still can't get Windows to boot.

The STOP code is actually A5 (and not 5A as reported earlier) and 
indicates an ACPI error of the available PCI resources, MS KB says:

"STOP 0x000000A5"
(0x00000002, Parameter2, Parameter3, Parameter4):
This error is defined as ACPI root PCI resource failure. To discover 
what current resources are being used by PCI devices, it must be able to 
query the CRS descriptor in the ACPI namespace. This error occurs 
because the BIOS lacks a pointer to the list, the list is empty, or 
contains errors/conflicts.

I haven't seen this before, so its most probably related to the 
passthrough and not so trivial as I initially assumed.

If I had keyboard access early in the bootup process I could press F7 to 
get the Standard-PC HAL (non-ACPI), but it seems the Bochs BIOS lacks 
USB HID support, so I only have the keyboard available when the OS is 
loading the drivers which is to late for Windows HAL selection...



Any ideas?


Thanks,
    Christian
