for controlling VirtualBox. The command and stderr is shown below.
Command: ["startvm", "c60f0594-d584-4e0b-b863-2801168e641e", "--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
