Invalid username or password
The default username / password to use when logging in to phpVirtualBox is admin / admin.
Some users have reported issues logging in if the PHP engine can't write to its session folder. It is impossible to cover all the possible PHP configurations here, so difficult to give direct guidance. I suggest you google
"php failed to write session data" adding your operating system to the search.
기본적으로 계정설정하는것 말고, 웹인터페이스 자체의 암호는 admin/admin 입니다
