[Xen-devel] The issue of booting windows guest

["Xu, Dongxiao" <dongxiao.xu@xxxxxxxxx>]

Hi, Keir, 
      In our nightly test, most of the windows guests cannot boot. And
my colleague and I checked this issue and find that this issue is caused
by C/S 17693. Some code in that changeset is:

@@ -196,6 +191,12 @@ static void pci_setup(void)
 
         switch ( class )
         {
+        case 0x0300:
+            if ( (vendor_id == 0x1234) && (device_id == 0x1111) )
+                virtual_vga = VGA_std;
+            if ( (vendor_id == 0x1013) && (device_id == 0xb8) )
+                virtual_vga = VGA_cirrus;
+            break;
         case 0x0680:
             ASSERT((vendor_id == 0x8086) && (device_id == 0x7113));
             /*

In "case 0x0300", the code should not break, and it shall execute the
following default code to do memory mappings. 


Best Regards,
