Re: [Qemu-devel] Creating a dummy PCI device

[Frederic Konrad]

Hi Peter,

This won't be easy unfortunately, at least not clean :).
The vendor_id device_id are part of the PCIDeviceClass.
So I _think_ you can't use a qom parameter for that.
But... it seems that these fields are used firstly in
pci_qdev_realize (to be checked) so maybe it's okay to change them
later before the device is realized with a parameter..

This is really hackish.. sorry.. but that's a though :).
