+Any VirtualBox VM can be packages as Vagrant box. Find VM name or UUID with::
+
+  $ VBoxManage list vms
+
+Pass it to one of::
+
+  $ vagrant package --base $VM_NAME
+  $ vagrant package --base $VM_UUID
+  $ vagrant package --base $VM_NAME --output my.box
+  $ vagrant package --base $VM_UUID --output my.box
+
+If you are in Vagrant managed directory (with ``.vagrant`` subdirectory) it is as simple as::
+
+  $ vagrant package
+
+.. note:: Only one VM is packages even if Vagrant file defines several VMs.
+
+Import packages box::
+
+  $ vagrant box add --name $NAME /path/to/new.box
+  ...
+  $ vagrant init $NAME
+  ...
+  $ vagrant up
