重点在device_init_func参数的qemu_opts_foreach,在其中调用了qdev_device_add。而在qdev_device_add里面,重要的一行是调用了dev = DEVICE(object_new(driver));,而且上一行有个注释——/* create device */: DEVICE是一个宏,实际是OBJECT_CHECK,主要是是看看obj是否是TYPE_DEVICE的一个实例: #define DEVICE...

在qdev_device_add函数中,首先会调用object_new,创建object(object是所有instance实例的根结构),最终是通过调用每个virtio-pci-net相应DeviceClass里的instance_init创建实例。 static void virtio_net_pci_instance_init(Object *obj) {VirtIONetPCI *dev = VIRTIO_NET_PCI(obj); virtio_instance_init_common(obj,...

Description I'm trying to have two network interfaces in each qemu vm for fuzzing. I tried to achieve this goal with this configuration: { "target": "linux/amd64", ... "vm": { "count": 1, ... "qemu_args": "-device e1000,netdev=net1 -netd...
