           Summary: SAX is not mapping to the correct mouse device for Xen
                    PV guest
           Product: openSUSE 11.0
           Version: Final
          Platform: x86-64
        OS/Version: openSUSE 11.0
            Status: NEW
          Severity: Major
          Priority: P5 - None
         Component: SaX2
        AssignedTo: sndirsch@novell.com

opensuse 11.0 PV guest, SAX is not mapping to the correct mouse device because
the Xen mouse vendor ID has been changed.  Correct values is now being supplied
by hal/hwinfo. 

sles 10 sp2, hwinfo 12.48, used 0x210 for the vendor ID.  
opensuse 11.0 using hwinfo 15.2, now sets the real vendor ID as well as the
compatible ID.

SLES 10 SP2 PV guest, hwinfo 12.48, shows:
18: PS/2 00.0: 10500 PS/2 Mouse
  [Created at input.179]
  Unique ID: AH6Q.GNlNOiDK6yC
  Hardware Class: mouse
  Model: "Xen Virtual Pointer"
  Vendor: int 0x0210
  Device: int 0x0018 "Xen Virtual Pointer"

openSuSE 11, hwinfo 15.2, shows:
18: PS/2 00.0: 10500 PS/2 Mouse
  [Created at input.183]
  UDI: /org/freedesktop/Hal/devices/computer_logicaldev_input_0
  Unique ID: AH6Q.Gp9x6FAd_SD
  Hardware Class: mouse
  Model: "Xen Virtual Pointer"
  Vendor: 0x5853
  Device: 0xfffe "Xen Virtual Pointer"
  Compatible to: int 0x0210 0x0018
  Device File: /dev/input/mice (/dev/input/mouse0)

Second part of this problem is that "sysp -s mouse" output does not have a
valid RealDevice set.

SLES 10 SP2 PV guest, sysp, shows:
sysp -s mouse
  Mouse0    =>  Protocol   : explorerps/2
  Mouse0    =>  Device     : /dev/input/mice
  Mouse0    =>  Buttons    : 10
  Mouse0    =>  Wheel      : 1
  Mouse0    =>  Emulate    : 0
  Mouse0    =>  Name       : Xen Virtual Pointer
  Mouse0    =>  VendorID   : 0x0210
  Mouse0    =>  DeviceID   : 0x0018
  Mouse0    =>  Profile    : xen-mouse
  Mouse0    =>  RealDevice : /dev/input/event1
  Mouse0    =>  NutShell   : 0

openSuSE 11, sysp, shows:
sysp -s mouse
  Mouse0    =>  Protocol   : explorerps/2
  Mouse0    =>  Device     : /dev/input/mice
  Mouse0    =>  Buttons    : 10
  Mouse0    =>  Wheel      : 1
  Mouse0    =>  Emulate    : 0
  Mouse0    =>  Name       : Xen Virtual Pointer
  Mouse0    =>  VendorID   : 0x5853
  Mouse0    =>  DeviceID   : 0xfffe
  Mouse0    =>  Profile    : <undefined>
  Mouse0    =>  RealDevice : <undefined>
  Mouse0    =>  NutShell   : 0

I poked around in sax/sysp source code and found the following.  

For RealDevice, in sysp/lib/hw/mouse.c:MouseGetData()
SLES10:
   if (strstr (str->str,"event")) {
      strcpy(data->realdev,str->str);
   }
opensuse 11.0:
   if (strstr (str->str,"by-id")) {
      strcpy(data->realdev,str->str);
   }
