VM creation error

I am trying to create a VM using Virtual Box 6.1.6 using Windows 10 with Vagrant version 2.2.6. I am getting an error message after I enter the command “vagrant up”.
This is what I get:
Command: [“startvm”, “32dbd621-6928-4701-b978-ad32688e0a1”, “–type”, “headless”]

Sterr : VboxManage: error : VT-x is not available (VERR_VMX_NO>VMX)
VboxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ConsoleWrap, interface IConsole

Have anyone else encountered this problem?
