Paravirtualization Support : Oracle VM VirtualBox 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).
- Introduced Headless and Detachable start options :
USB 3.0 Devices
Bi-Directional Drag and Drop Support for Windows
Disk Image Encryption : Oracle VM VirtualBox 5.0 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.
