To see if virtualization is enabled, you need to check your computer's BIOS settings. It's like the secret menu of your computer, and it's usually accessed by pressing a key like F2 or DEL during boot-up. Once you're in, look for the Virtualization or VT-x setting and make sure it's turned on.
If you're using a Windows machine, you can also use the Task Manager to check if virtualization is enabled. Just press Ctrl + Shift + Esc, click on the Performance tab, and look for the Virtualization section. If it says "Enabled", you're good to go!
