<title>Using VBoxManage Commands for Unattended Guest Installation</title>
<body>
<p>The following example shows how to perform an unattended guest installation for an Oracle Linux VM.
The example uses various <userinput>VBoxManage</userinput> commands to prepare the guest VM. The
<userinput>VBoxManage unattended install</userinput> command is then used to install and configure the guest OS. </p>
<ol>
<li>
<p>Create the virtual machine. </p>
<pre xml:space="preserve"># VM="ol7-autoinstall"
# VBoxManage list ostypes
# VBoxManage createvm --name $VM --ostype "Oracle_64" --register</pre>
<p>Note the following: </p>
<ul>
<li>
<p>The $VM variable represents the name of the VM. </p>
</li>
<li>
<p>The <userinput>VBoxManage list ostypes</userinput> command lists the guest OSes
supported by <ph conkeyref="vbox-conkeyref-phrases/product-name"/>, including the name used for each OS in
the <userinput>VBoxManage</userinput> commands. </p>
</li>
<li>
<p>A 64-bit Oracle Linux 7 VM is created and registered with <ph
conkeyref="vbox-conkeyref-phrases/product-name"/>. </p>
</li>
<li>
<p>The VM has a unique UUID. </p>
</li>
<li>
<p>An XML settings file is generated. </p>
</li>
</ul>
</li>
<li>
<p>Create a virtual hard disk and storage devices for the VM. </p>
<pre xml:space="preserve"># VBoxManage createhd --filename /VirtualBox/$VM/$VM.vdi --size 32768
# VBoxManage storagectl $VM --name "SATA Controller" --add sata --controller IntelAHCI
# VBoxManage storageattach $VM --storagectl "SATA Controller" --port 0 --device 0 \
--type hdd --medium /VirtualBox/$VM/$VM.vdi
# VBoxManage storagectl $VM --name "IDE Controller" --add ide
# VBoxManage storageattach $VM --storagectl "IDE Controller" --port 0 --device 0 \
--type dvddrive --medium /u01/Software/OL/OracleLinux-R7-U6-Server-x86_64-dvd.iso</pre>
<p>The previous commands do the following: </p>
<ul>
<li>
<p>Create a 32768 MB virtual hard disk. </p>
</li>
<li>
<p>Create a SATA storage controller and attach the virtual hard disk. </p>
</li>
<li>
<p>Create an IDE storage controller for a virtual DVD drive and attach an Oracle Linux
installation ISO. </p>
</li>
</ul>
</li>
<li>
<p>(Optional) Configure some settings for the VM. </p>
<pre xml:space="preserve"># VBoxManage modifyvm $VM --ioapic on
# VBoxManage modifyvm $VM --boot1 dvd --boot2 disk --boot3 none --boot4 none
# VBoxManage modifyvm $VM --memory 8192 --vram 128</pre>
<p>The previous commands do the following: </p>
<ul>
<li>
<p>Enable I/O APIC for the motherboard of the VM. </p>
</li>
<li>
<p>Configure the boot device order for the VM. </p>
</li>
<li>
<p>Allocate 8192 MB of RAM and 128 MB of video RAM to the VM. </p>
</li>
</ul>
</li>
<li>
<p>Perform an unattended install of the OS. </p>
<pre xml:space="preserve"># VBoxManage unattended install $VM \
--iso=/u01/Software/OL/OracleLinux-R7-U6-Server-x86_64-dvd.iso \
--user=<varname>login</varname> --full-user-name=<varname>name</varname> --user-password <varname>password</varname> \
--install-additions --time-zone=CET</pre>
<p>The previous command does the following: </p>
<ul>
<li>
<p>Specifies an Oracle Linux ISO as the installation ISO. </p>
</li>
<li>
<p>Specifies a login name, full name, and login password for a default user on the guest
OS. </p>
<p>Note that the specified password is also used for the root user account on the guest. </p>
</li>
<li>
<p>Installs the Guest Additions on the VM. </p>
</li>
<li>
<p>Sets the time zone for the guest OS to Central European Time (CET). </p>
</li>
</ul>
</li>
<li>
<p>Start the virtual machine. </p>
<p>This step completes the unattended installation process. </p>
<pre xml:space="preserve"># VBoxManage startvm $VM --type headless</pre>
<p>The VM starts in headless mode, which means that the <ph
conkeyref="vbox-conkeyref-phrases/vbox-mgr"/> window does not open. </p>
</li>
</ol>
