1. 查看笔记本ip信息
1 | ifconfig |
会输出如下信息:

eno1网卡的信息
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | TYPE="Ethernet" PROXY_METHOD="none" BROWSER_ONLY="no" BOOTPROTO="dhcp" DEFROUTE="yes" IPV4_FAILURE_FATAL="no" IPV6INIT="yes" IPV6_AUTOCONF="yes" IPV6_DEFROUTE="yes" IPV6_FAILURE_FATAL="no" IPV6_ADDR_GEN_MODE="stable-privacy" NAME="eno1" UUID="b6ad092a-6096-4977-a96e-74d9a153def6" DEVICE="eno1" ONBOOT="yes" ZONE=public |
2. 新建一张网卡brv
1 2 | cd /etc/sysconfig/network-scripts vi ifcfg-brv |
输入如下信息:
1 2 3 4 5 6 7 8 | DEVICE=brv TYPE=Bridge ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=static IPADDR=192.168.50.122 NETMASK=255.255.255.0 GATEWAY=192.168.50.255 |
3. 重启系统,就可以看到已经激活的网卡了
4. 把这网卡添加到kvm22虚拟机中
1 2 | virsh attach-interface kvm22 --type bridge --source brv //临时添加,重启失效 virsh attach-interface kvm22 --type bridge --source brv --config //永久添加. |
5. 查看虚拟机网卡就能看到已经添加成功
1 | virsh domiflist kvm22 |
6. 把网卡信息写入虚拟机,以免失效
1 | virsh dumpxml kvm22 > /etc/libvirt/qemu/kvm22.xml |
7. 删除网卡命令
1 | virsh detach-interface kvm22 --type bridge --mac 52:54:00:fb:f5:d6 |
备注:
上面这方法加的是静态IP,只能访问笔记本,无法访问虚拟机.
