Oracle has released VirtualBox 4.2 beta 1 today, which includes some major improvements, like improved Windows 8 support, an expert mode for wizards, experimental support for drag’n’drop from the host to Linux guests and more.
Changes in VirtualBox 4.2 beta 1:

  • Improved Windows 8 support, in particular many 3D-related fixes
  • GUI: VM groups
  • GUI: expert mode for wizards
  • GUI: allow to alter some settings during runtime
  • Support for up to 36 network cards, in combination with an ICH9 chipset configuration
  • Resource control: added support for limiting network IO bandwidth
  • Added possibility to start VMs during system boot on Linux, OS X and Solaris
  • Added experimental support for Drag’n’drop from the host to Linux guests. Support for more guests and for guest-to-host is planned.
  • Support recent VIA CPUs
  • Allow taking screenshots of the current VM window content
  • Allow automatically sorting of the VM list
  • Allow starting of headless VMs from the GUI
  • GUI: network operations manager
  • Improved VM context switch performance for Intel CPUs using nested paging
  • Added support for FlushByASID features of AMD CPUs (Bulldozer and newer)
  • Added readonly support for VHDX images, QED images and for QCOW (full support for v1 and readonly support for v2) images
  • Bug fixes


Since VirtualBox 4.2 is in beta, you will find bugs so don’t use this on a production machine! If you encounter bugs, report them on the VirtualBox Beta Feedback forum. For instance, in my test using Linux (Ubuntu) for both the guest and host machine, the new experimental drag’n’drop feature didn’t work for some reason – if you figure out how to get it to work, let us know in the comments!
For how to use some of the new features, like limiting network I/O bandwidth or staring a VM on system boot, see the VirtualBox manual, available via the download link below.


Download VirtualBox 4.2 beta 1 for Linux, Windows or Mac OS X

Update: VirtualBox 4.2.0 RC1 is now available for download @

Note: to be able to install VirtualBox 4.2 beta 1 in Ubuntu, you must firstly remove any installed VirtualBox version. For instance, if you have installed the latest stable VirtualBox 4.1, remove it using the following command:
sudo apt-get remove virtualbox-4.1

And then simply install the VirtualBox 4.2 beta 1 downloaded deb file.

Αν υπάρχει ένα λειτουργικό σύστημα που πραγματικά αναπτύσσεται ραγδαία αυτό φυσικά δεν είναι άλλο από το Linux. Αν και ξεκίνησε σαν μια πολύ ταπεινή προσπάθεια του τότε φοιτητή Linux Torvalds, αυτή τη στιγμή χρησιμοποιείται σε κάθε είδους συσκευή. Από smartphones και tablets μέχρι τηλεοράσεις και υπερυπολογιστές. Σε τι οφείλει όμως την τεράστια επιτυχία του;

Κυρίως στο γεγονός ότι στην ανάπτυξη του συμμετέχουν προγραμματιστές και εταιρείες απ’ όλο τον κόσμο. Μάλιστα όπως ανέφερε το Linux Foundation περίπου 8.000 άτομα από διάφορες χώρες του κόσμου έλαβαν μέρος στην ανάπτυξη του κατά το 2011.

Ανάμεσα τους προγραμματιστές και προσωπικό διαφόρων μεγάλων εταιρειών όπως η IBM, η Intel, η Nokia ακόμη και η Microsoft (δεν πρόκειται για λάθος) η οποία μάλιστα είναι 17η σε ό,τι αφορά τις προσθήκες σε κώδικα.

Επιπλέον, με την επανενοποίηση του πυρήνα του Linux με αυτόν του Android, είναι βέβαιο ότι εταιρείες όπως η Google και η Samsung θα αναδειχθούν ακόμη περισσότερο σε ό,τι αφορά την εξέλιξη του λειτουργικού.
