Vagrant VirtualBox不希望为虚拟机打开会话

我对流浪者和virtualbox（virtualbox qt 4.3.10-dfsg-1ubuntu2）有问题。当我执行命令：

vagrant up

时，我收到以下消息：

Bringing machine 'default' up with 'virtualbox' provider...
==> default: Checking if box 'ubuntu/trusty32' is up to date...
==> default: Clearing any previously set forwarded ports...
==> default: Clearing any previously set network interfaces...
==> default: Preparing network interfaces based on configuration...
    default: Adapter 1: nat
==> default: Forwarding ports...
    default: 8080 => 6389 (adapter 1)
    default: 22 => 2222 (adapter 1)

==> default: Booting VM...
==> default: Waiting for machine to boot. This may take a few minutes...
The guest machine entered an invalid state while waiting for it
to boot. Valid states are 'starting, running'. The machine is in the
'poweroff' state. Please verify everything is configured
properly and try again.

If the provider you're using has a GUI that comes with it,
it is often helpful to open that and watch the machine, since the
GUI often has more helpful error messages than Vagrant can retrieve.
For example, if you're using VirtualBox, run `vagrant up` while the
VirtualBox GUI is open.

在启动时运行虚拟机时，出现以下错误：

Failed to open a session for the virtual machine booklock_server_default_1427275442366_68003.

VT-x is not available. (VERR_VMX_NO_VMX).

VirtualBox正在尝试使用硬件虚拟化。检查您的硬件是否支持vt-x，然后确保它已在BIOS中启用。如果您没有硬件虚拟化或无法在您的计算机上启用它，很遗憾您将无法在VirtualBox中运行64位来宾操作系统，请参阅：

这似乎不是一个编程问题。感谢您的回复。我使用了这个命令：egrep-c'（vmx | svm）/proc/cpuinfo，得到了0。这意味着我的机器不支持虚拟化，那又如何？如果没有硬件虚拟化，您只能使用一个CPU的32位来宾操作系统运行VM，请参阅Virtualbox中我已将Ubuntu设置为32位
