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。
