Pan0 NIC and virbr0 nic removal issues under Linux

Long time no blog, was because of lazy, and now a bit of a moment, found that blogging or some role, can help many people solve problems, and sometimes forget, but also can look back. My environment is centos6.5, installed in the virtual machine.

Recently, when I restarted the network, I found that there are so many network cards in the Linux system, I feel baffled, 650) this.width=650; "Src=" http://s3.51cto.com/wyfs02/M00/89/DC/ Wkiol1gggsbcs6xkaaaabvwuucw831.png-wh_500x0-wm_3-wmp_4-s_466486934.png "title=" 41.png "alt=" Wkiol1gggsbcs6xkaaaabvwuucw831.png-wh_50 "/>

Looked under: ifconfig-a

By checking the data found that Pan0 is a Bluetooth device, VIRBR0 is a virtual network card (that is, the system comes with)

Then I have to find a way to delete ah, on-line check, pan0 of the removal of almost no, I think of the next, since it is Bluetooth is definitely hardware equipment, so fdisk-l see there is no redundant equipment, found no, then I found here, first service Bluetooth

Stop, hang up the Bluetooth service

Because it is a Bluetooth device that is shared with the host, I can't see it. The "Share Bluetooth with virtual machine" before the tick to remove, so as to solve the problem of pan0.

The following resolves virbr0 and virbr0-nic

Execute the Yum groupremove "virtualization" command to attempt to uninstall the VIRBR0 device, ifconfig-a see if the VIRBR0 device is still present;
2, if still did not uninstall the VIRBR0 network card, then execute this command: Yum remove Libvirt, with ifconfig-a to see if the NIC virbr0 uninstall.
3, if the implementation of Yum error, you can vi/etc/yum/plugincon.d/rhnplugin.conf and then change the file enable=1 to enable=0, the purpose is to disable this feature, and then perform the Yum remove Libvirt Uninstall.

When the uninstallation is complete restarting the machine, several of the above NICs do not exist.
