How to Fix the "VT-x is not available" in VirtualBox

I recently ran across this error when moving a VM to a different machine. To fix it:

• Close VirtualBox
• Go into the VM folder (usually inside a folder like VirtualBox VMs) and open the text file ending in .vbox.
• Look for a line like <HardwareVirtEx enabled="true"/> and change it to <HardwareVirtEx enabled="false"/>.

That should fix the "VT-x is not available" error.
