Ao enviar o comando "vagrant up" pela primeira vez, aparece esse erro. Estou utilizando uma vm no VirtualBox emulando um Ubuntu (para emular o Linux do Vagrantfile proposto na aula).
There was an error while executing VBoxManage, a CLI used by Vagrant for controlling VirtualBox. The command and stderr is shown below.
Command: ["startvm", "bb1608dd-f60f-4a7b-b5cb-3c02fa2ffc87", "--type", "headless"]
Stderr: VBoxManage: error: VT-x is not available (VERR_VMX_NO_VMX) VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ConsoleWrap, interface IConsole
