我正在为80211模块设置一个内核testing虚拟机。
我用这个命令启动我的机器：
kvm -m 512 -net nic -net vde -usb -usbdevice host:0ace:1215 ktesting.img 我用debian连接到eth0接口的vde_switch，并设置了一个kvm镜像
Bus 003 Device 004: ID 0ace:1215 ZyDAS ZD1211B 802.11g
我安装了'zd1211-firmware'，并在/ dev / bus / usb中提供了正确的权限。
wlan0接口上去了：
eth0 Link encap:Ethernet HWaddr 52:54:00:12:34:56 inet addr:192.168.2.15 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:fe12:3456/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7 errors:0 dropped:0 overruns:0 frame:0 TX packets:13 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1706 (1.6 KiB) TX bytes:1458 (1.4 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) wlan0 Link encap:Ethernet HWaddr 00:02:72:71:dc:a3 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
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）：

我尝试使用我的笔记本电脑上的WiFi适配器连接到相同的configuration文件只安装zd1211固件相同的networking，它完美的工作。 这不是我编译的内核的问题，因为问题仍然存在于股票debian内核（wheezy）
