Changing the XI Virtual Machine Network Configuration

Project Notes

<p>To change the virtual machine network configuration settings, follow these steps:</p>

<p>1. Login to the machine as the root user</p>
<p>2. Install the system network configuration TUI</p>
<pre>yum install -y system-config-network-tui</pre>
<p>3. Run the system network config tool from the command line</p>
<pre>system-config-network-tui</pre>
<p>The config tool allows you to change the DNS information and network card settings on the virtual machine.</p>
<p>4. Once you've made the appropriate changes in the configuration tool, run these commands from the command line to activate the virtual machine's network card with the updated configuration.</p>
<pre>ifdown eth0<br />ifup eth0<br /></pre>
<p>5. You can verify the network settings by using the ifconfig command like this:</p>
<pre>ifconfig eth0</pre>

<p>That's it!</p>
<p>A quick video that takes you through the process of running the network configuration tool is available below.</p>

<b>Important:</b> If has been observed that sometimes the system-config-network or nmtui tool removes the localhost entries from the /etc/hosts file. In order to fix the issue, edit your /etc/hosts file and make sure there are localhost entries. For example:
</p>

<pre>127.0.0.1 localhost.localdomain localhost.localdomain localhost4 localhost4.localdomain4 localhost xi-c6x-x64
::1 localhost.localdomain localhost.localdomain localhost6 localhost6.localdomain6 localhost xi-c6x-x64</pre>
