KvmWithBridge：主网络接口（wi-fi）

如何建立桥接网络？

示例interfaces附带eth0定义 – 我正在使用Wi-Fi。 虽然有一个以太网端口，但它没有被使用。

没有部分上述interface文件The primary network interface 。 这是网络信息：

 thufir@dur:~$ thufir@dur:~$ ifconfig eno1: flags=4099 mtu 1500 ether c8:9c:dc:28:86:ca txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 20 memory 0xfe700000-fe720000 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 5815 bytes 531107 (531.1 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 5815 bytes 531107 (531.1 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 virbr0: flags=4099 mtu 1500 inet 192.168.122.1 netmask 255.255.255.0 broadcast 192.168.122.255 ether 52:54:00:20:ba:e1 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 wlx74da3889c88b: flags=4163 mtu 1500 inet 192.168.1.5 netmask 255.255.255.0 broadcast 192.168.1.255 inet6 fe80::cde:e1f7:5175:b3c0 prefixlen 64 scopeid 0x20 ether 74:da:38:89:c8:8b txqueuelen 1000 (Ethernet) RX packets 72332 bytes 72736092 (72.7 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 61239 bytes 9854513 (9.8 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 thufir@dur:~$ 

它是wlx74da3889c88b ，表示与路由器的Wi-Fi连接，默认网关为192.168.1.1 。 使用wlx74da3889c88b作为“主网络接口”？

也许它根本不适用于Wi-Fi。
