Ubuntu12.04 configure KVM to use Nic Bridging Mode

In the past, CentOS6 was changed because UbuntuServer did not solve Nic bridging because of kvm. It is easier to configure Bridging for Centos6 and supports VirtualMachineManager, but it is not ideal to manage virtual machines only with root. Now try again to configure the javastuserver Nic bridging, and find it is actually very simple 1. Install the minimal installation of javastuserver12.04, only enable OPEN

In the past, CentOS6 was changed Because Ubuntu Server did not solve Nic bridging during kvm. It is relatively easy to configure Bridging for Centos6 and supports Virtual Machine Manager, but it is not ideal to only use root to manage Virtual machines.

Now I try again to configure the Ubuntu Server Nic bridging, and it is actually very simple.

1. Install

Install Ubuntu Server 12.04 with only open ssh enabled. After installation:

2. Use Virtual Machine Manager to test the connection. The following error message is displayed:
