Oracle Linux 6 Bridging network adapter

Oracle Linux 6 Bridging network adapter

Recently, the company has been a stale old HP format for Linux virtualization, install some test servers. The operating system uses Oracle Linux 6.4, and the virtual machine uses KVM.

The front installation is very smooth, but to set up the network card bridge when there is a problem, like the previous 5.x set the BR0 configuration file is useless, as long as a bridge will be wrong, the network card and bridge the virtual network card error.

1

Eth0:connection activation Failed:master Connection not found or invalid

2

Br0:conncetion activation failed:failed To determine connection ' s virtual Interface name

But the configuration bridge file should be correct, and finally through the online view, just know is networkmanager problem.

Follow the instructions to stop NetworkManager service

1

Service NetworkManager Stop

And then re-execute

1

Service Network restart

The network adapter bridge configuration was successful. I estimate that many tutorials on the web are written on a purely command-line basis, and many configurations may not be the same if the desktop is installed separately.
