从Oracle虚拟盒加载Puppet图像时出现此错误.我该如何解决？

Failed to open a session for the virtual machine learn-puppet-centos-6.4-pe-3.1.0.

VT-x is disabled in the BIOS. (VERR_VMX_MSR_VMXON_DISABLED).

Result Code: E_FAIL (0x80004005)
Component: Console
Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

另外,我看到acellerateVirtual Box 中的-tab被禁用.
