Do you consider allowing support for Windows as overengineering?

I don't think there is a way to hook BSOD on Windows so attempting to
engineer something that works with Windows seems odd, no?

Yan says in other email that is is possible to register a bugcheck callback.

Here you go - http://msdn.microsoft.com/en-us/library/windows/hardware/ff553105(v=vs.85).aspx
Already done in virtio-net for two reasons: 1. we could configure virtio-net to notify QEMU in a hacky way (write 1 to VIRTIO_PCI_ISR register) that there was a bugckeck .It was very useful debugging complex WHQL issues that involved host networking. 2. Store additional information (for example time stamps of last receive packet, last interrupt and etc) in crash dump.
