VirtualBox in version 5.0 offers also the possibility to encrypt virtual disks in addition to USB 3.0. Windows and Linux guest systems should be accelerated with a first implementation of paravirtualization.

The version 5.0 of virtualization VirtualBox is known as major release. Including disk images can be encrypted in the future, guests can access USB 3.0 devices and a new paravirtualization to increase speed of Windows and Linux guest systems.

The paravirtualization, VirtualBox 5.0 introduced guest systems can access interrupt controller (APIC) of the host such as OS X and Windows version 7, for example, on the clock frequency of the advanced programmable. For a Hyper-V interface implemented in VirtualBox, which can also access various timer of the host. FreeBSD should benefit from this interface.

A KVM interface available, which also provides timers is available for Linux guests. The paravirtualization to facilitate cooperation between guests and hosts in total. For guest systems, more instructions for external hardware available, including SSE 4.1, SSE 4.2 and access are also on the Kryptomodul of AES-NI in processors.

External disk encrypted

Developers have also invested much work in the USB stack. About the new Xhci driver that supports USB 3.0 devices, also USB hard disk as a virtual data store can be integrated in VirtualBox. Also the traffic can be cut with in the future via the USB interface. Virtual SATA hard disks can be running on or hang out (hotplugging).

VirtualBox 5.0 supports USB 3.0Also virtual hard disk images can now be encrypted. To do this, a dialog box under the heading General has been integrated. The choices are so far AES-XTS256-PLAIN64 or AES-XTS128-PLAIN64. Through the graphical interface, it encrypts, however, all disk images that are allocated to the virtual machine. All will receive a single password that must be entered when starting. Selected images can be, however, via the command line with VBoxManage encrypt and with individual passwords. Is elected there always the same password, it queried only once at startup. Encrypted disks can be decrypted again.

Virtual machines can be started via the UI in the background. In the so-called headless mode it running also when closes the window or the entire GUI of VirtualBox.

Optimized presentation

Also on the graphical interface, the developers have filed. The menus and status bars can be adjusted now individually for each virtual machine. Drag-and-drop works both ways in Windows, Linux, and Solaris guest systems. The contents of guest systems can scale in the future, even if 3D acceleration is enabled. Optimizing for retina display (HiDPI) was implemented for the operation under Mac OS X and Windows. In addition have the developer modularize the audio stack, to enable a better integration in the sound system of a host.

Windows 10 is now supported as a guest system. Also run Linux systems with native Systemd support. VirtualBox 5.0 itself can be on systems running OS X 10.10 alias use Yosemite, Windows Server 2012 R2 and 22 Fedora and Ubuntu 15.04.
