我在终端输入“vagrant up”并得到以下结果：
/opt/vagrant/bin/../embedded/gems/gems/vagrant-1.7.1/lib/vagrant/pre-rubygems.rb:31: warning: Insecure world writable dir /usr/local/sbin in PATH, mode 040777

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.
我尝试在打开 VirtualBox GUI 的情况下执行此操作，但得到了同样的结果。
另外，如果我尝试在 GUI 中启动它，我会得到以下信息：
Failed to open a session for the virtual machine FlarumVm.
Failed to load VMMR0.r0 (VERR_SUPLIB_WORLD_WRITABLE).
Result Code: NS_ERROR_FAILURE (0x80004005)

有什么建议吗？谢谢！（顺便说一句，我在 bios 中启用了虚拟化。
