Here is how Baidu knows how to handle

Solution:
Delete/home/user/directly under Linux. Virtualbox/virtualbox.xml file, which is created automatically when the virtual machine starts, so there is no need to worry about deleting it.
Like under Windows, delete c:\users\administrator/. Virtualbox\virtualbox.xml
