Re: [Qemu-devel] qemu sources and makefile system

[Vasile Catalin-B50542]

    Thanks. It will be helpful in the future.
    I managed to make it work. The code was included, but I forgot to
    register the device type on the virtio-pci bus.
    
    static void virtio_pci_register_types(void)
    {
    Â Â Â  /* ... */
    Â Â Â  type_register_static(&virtio_src_pci_info);
    Â Â Â  /* ... */
    }
