[Xen-users] Windows driver failed to start in Windows HVM with PCI Passthrough

[John Mok <a9121431@xxxxxxxxx>]

Hi,

I am using Xen 4.6 on Debian Jessie 8.2 :-

Host dom0
=========
Kernel 3.16.0
Xen 4.6.0
QEMU 2.1 and QEMU 2.5

Windows HVM
===========
Windows 7 SP1 64-bit
Intel AC 7265 driver 18.21

The WiFi adapter driver failed to start with error code 10. The
Winodws system logs showed 2 errors :-

1. Event ID 5001 - Could not allocate the resources necessary for operation
Event data : \Device\NDMP6

2. Event ID 5006 - The version number is incorrect for this driver
Event data : \Device\NDMP6

The Windows driver worked fine on bare-metal,but failed to start in
HVM with PCI Passthrough.
The Linux driver iwlwifi also worked fine in domU with PCI Passthrough (PV).

Is there anyone knows how to make the Windows driver work in HVM with
PCI Passthrough (e.g. patch hvmloader or something) ?

Thanks a lot.

John Mok
