我正在尝试为 80211 模块设置内核测试虚拟机。
我使用以下命令启动我的机器：
kvm -m 512 -net nic -net vde -usb -usbdevice host:0ace:1215 ktesting.img
我设置了一个 kvm 映像，其中 debian 连接到 eth0 接口上的 vde_switch，并且
Bus 003 Device 004: ID 0ace:1215 ZyDAS ZD1211B 802.11g
我安装了“zd1211-firmware”并在 /dev/bus/usb 中赋予了正确的权限。
wlan0 接口启动：

但是当我尝试使用 wpa_supplicant 连接到我的路由器时：
wpa_supplicant -i wlan0 -c conf
我得到了这个输出（stderr 和 stout）：

我尝试使用笔记本电脑上的 wifi 适配器连接到同一个网络，使用同一个配置文件，只安装 zd1211-firmware，它工作正常。这不是我编译的内核的问题，因为问题仍然存在于库存 debian 内核（wheezy）
我尝试将其发布在 serverfault 上，因为我不确定它是否正确，而且我没有答案，所以我也会将其发布在那里
