How to Fix “VBoxManage: error: AMD-V is disabled in the BIOS (or by the host OS)” When Virtualbox Starts

There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.
Command: ["startvm", "f1cd5563-6150-4968-b605-43b9a367a148", "--type", "headless"]
Stderr: VBoxManage: error: AMD-V is disabled in the BIOS (or by the host OS) (VERR_SVM_DISABLED)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ConsoleWrap, interface IConsole

AMD-V stands for AMD Virtualization. AMD-V enables you to run multiple virtual machines on a single machine. This error is telling you that your BIOS has AMD-V disabled. You need to re enable AMD-V to get rid of the error. To do so:

1. Reboot and repeatedly press your BIOS System Settings key
2. Open Advanced Settings or similar
3. Open CPU settings
4. Look for a virtualization option. Mine was labeled as SVM.
5. Enable it
6. Save and reboot into your OS
7. You’re done!

I hope this fixed your problem. If it didn’t leave a comment and I’ll see if I can give you a hand
