Virtualbox is under GPL-2 with a lot of exception, allowing it to be used with MPL, Apache 2.0, OpenSSL.So, LGPL-3 will be too restrictive I think for them.It should be fine to combine GPL-2 and LGPL-3.
No, GPLv2 and LGPLv3 are not compatible: https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility -- Jakub Wilk
