Setup Issue for Ubuntu

As I advance to the Configuration phase(Local Development - Pressbooks), with some assistance from other sources, I’ve run into an error while trying to execute ‘vagrant up.’ Any guidance or insights on resolving this issue would be highly appreciated.

There was an error while executing VBoxManage, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: [“startvm”, “6788e138-b257-4d69-832b-6000d7cecb87”, “–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
