Today I installed Windows Xp in Virtuabox however happen an error.

VT-x is not available
Unknown error creating VM

So How to solve this problem？Do it：

In VirtualBox 3.0.2, this option no longer appears in the Advanced pane. Nevertheless I managed to find a workaround to deselect the option despite it no longer appearing in the UI:

Under the ~/Library/VirtualBox/Machines directory you will find a folder for each virtual machine you have created. Within this directly you will find an XML file with the machine settings.

It looks like:

 13     </ExtraData>
 14     <Hardware version="2">
 15       <CPU count="1">
 16         <HardwareVirtEx enabled="true" exclusive="false"/>
 17         <HardwareVirtExNestedPaging enabled="true"/>
 18         <HardwareVirtExVPID enabled="true"/>
 19         <PAE enabled="true"/>
 20       </CPU>

Just change the 'enabled="true"' part to 'enabled="false"'.

Enjoy.
