Fedora pan0、virbr0 卸載 教程

在進行網絡配置的時候，硬件有eth0、pan0以及virbr0 三個，
eth0物理網卡、virbr0 應該是虛擬網卡吧、pan0藍牙設備

PAN的實現技術主要有：Bluetooth、IrDA、Home RF與UWB（Ultra-Wideband Radio）四種

1、請先將雙機的JOB帶出，執行 yum groupremove "Virtualization" 命令嘗試卸載virbr0設備，通過ifconfig -a查看virbr0設備是否還存在；
2、如果還是沒有卸載掉virbr0網卡，再執行一下這個命令：yum remove libvirt ，用ifconfig -a查看網卡virbr0是否卸載。
3、如果執行yum報錯， 可以vi /etc/yum/plugincon.d/rhnplugin.conf然後將文件中的enable=1改成enable=0，目的是先禁用此功能，再執行yum remove libvirt進行卸載。

卸載完成重啟機器，虛擬網卡就不存在。
