Description Buck Huppmann 2009-09-04 13:53:50 UTC

Description of problem:
Note:  This is not a problem on Debian, with kvm-72, but
apparently is on Red Hat, with kvm-83.  It may not even be
your bug, but just a serendipitous bug in the Debian ver-
sion that just happens to do what Windows expects/is conf-
figured to expect, and, since i can fix this pretty easily,
i'm mostly just throwing it out here in case it's useful
reference for somebody else, as i doubt that this is a re-
gression

A Windows(TM) XP image created using GHOST that boots up
fine on physical hardware (and on Debian, as noted previous-
ly) fails to detect the emulated pcnet NIC as the Allied Tele-
syn NIC for which it has a driver configured, so networking
fails, unless you manually configure the NIC to use the

This seems to be because the emulated pcnet NIC reports a
PCI subsystem ID of 20000000, whereas the driver wants 00000000,
and that's what Debian's KVM/QEMU gives it, as well

Version-Release number of selected component (if applicable):
kvm-83-105.el5

How reproducible:
Try to run a Windows XP image configured with the Allied
Telesyn driver (details below) with -net nic,model=pcnet

Steps to Reproduce:
1. /usr/libexec/qemu-kvm -net nic,model=pcnet
2.
3.
  
Actual results:
NIC not found by WinXP driver

Expected results:
NIC found by WinXP driver

Additional info:
Driver is
  Allied Telesyn AT-2450T/AT/BT/FT PCI 10Mb
  atnicm51.sys
  version 4.47.0, 7/2/2004
