Some of the new features of Oracle VM VirtualBox are:
Paravirtualization support for modern Windows and Linux guests
It is able to expose a paravirtualization interface to facilitate accurate and efficient execution of software. Once the virtual machine platform is defined, Oracle VM VirtualBox improves guest OS performances by leveraging built-in virtualization support (KVM on Linux guests and Hyper-V on Windows guests).
xHCI controller to support USB 3.0 devices
Guest operating systems are now able to directly recognize USB 3.0 devices and operate at full 3.0 speeds. Guest can now be configured to use USB 1.1, 2.0 and 3.0 devices.
Improved Drag & Drop support
Starting from Oracle VM Virtual Box improved the support of a bi-directional drag&drop between guest and host operating system; drag and drop support is available with latest guest-additions installed.
Disk image encryption
Oracle VM Virtual Box allows for encrypted virtual disk images by leveraging AES algorithm in XTS mode (128-bit or 256-bit); since the DEK is stored as part of the virtual machine configuration file, encryption introduces a further security feature that will ask for a password while starting the virtual machine.
Headless and Detachable start options
It now supports starting virtual machines in the background with a separate front-end process that can be closed while the virtual machine continues to work.
Note: To extend VirtualBox capabilities it's recommended to download and install VirtualBox Extension Pack.
