1、查看原有网卡信息 root@localhost ~]# virsh domiflist centos73 Interface Type Source Model MAC ------------------------------------------------------- vnet1 bridge br0 virtio 52:54:00:9d:7a:94 2、临时添加新网卡 # [root@localhost ~]# virsh attach-interface centos73 --type bridge --source br0 Interface attached successfully 成功附加接口 永久添加网卡命令 #virsh attach-interface centos73 --type bridge --source br0 --config 3、查看 [root@localhost ~]# virsh domiflist centos73 Interface Type Source Model MAC ------------------------------------------------------- vnet0 bridge br0 virtio 52:54:00:9d:7a:94 vnet1 bridge br0 rtl8139 52:54:00:c4:8d:84 Last login: Mon Aug 21 21:27:27 from 192.168.0.190 [root@localhost ~]# ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.0.112 netmask 255.255.255.0 broadcast 192.168.0.255 inet6 fe80::1e89:5915:c6b6:2eb1 prefixlen 64 scopeid 0x20<link> ether 52:54:00:c4:8d:84 txqueuelen 1000 (Ethernet) RX packets 29 bytes 4669 (4.5 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 35 bytes 3334 (3.2 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.0.172 netmask 255.255.255.0 broadcast 192.168.0.255 inet6 fe80::5054:ff:fe9d:7a94 prefixlen 64 scopeid 0x20<link> ether 52:54:00:9d:7a:94 txqueuelen 1000 (Ethernet) RX packets 59 bytes 12755 (12.4 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 9 bytes 1246 (1.2 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1 (Local Loopback) RX packets 8 bytes 680 (680.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 8 bytes 680 (680.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 4、命令行增加的网卡只保存在内存中，重启就失效，所以需要保存到配置文件中 virsh dumpxml centos73 > /etc/libvirt/qemu/centos73.xml virsh define /etc/libvirt/qemu/centos73.xml Domain centos73 defined from /etc/libvirt/qemu/centos73.xml 删除网卡命令 #virsh detach-interface centos73--type bridge --mac 52:54:00:c4:8d:84
