+chmod 700 .ssh
+chmod 600 .ssh/authorized_keys
+chown -R vagrant:vagrant .ssh
+```
+
+或者直接拷贝原打包目录.vagrant下的privacy key
+
+### mount: unknown filesystem type 'vboxsf'问题
+
+```bash
+vagrant plugin install vagrant-vbguest
+vagrant destroy && vagrant up
+```
+

+
+```bash
+vagrant plugin install vagrant-winnfsd
+```
+
+
