Software Update: VirtualBox 3.1.8

Oracle released version 3.1.8 of VirtualBox on Monday, the fourth update to version 3.1.0, which was released in early December. This program can be used to install other operating systems on a computer in a virtual environment. That way, different OSes can be used on the same hardware. VirtualBox is available for Windows 2000 and above, Mac OS X, Linux, and Solaris, and can handle a variety of guest operating systems.

VirtualBox is available in two versions. The full version has additional functionality, such as support for USB ports and the remote display protocol, but it is only free for private use and evaluation purposes. This extra functionality is closed source and is therefore not present in the open source version. Version 3.1.8 is a maintenance release and the changelog mainly shows bug fixes:

The following items were fixed and/or added:

  • VMM: fixed crash with the OpenSUSE 11.3 milestone kernel during early boot (software virtualization only; bug #5457)
  • VMM: fixed invalid state during teleportation
  • VMM: fixed OS/2 guest crash with nested paging enabled
  • VMM: fixed massive display performance loss (AMD-V with nested paging only)
  • GUI: fixed off-by-one bug when passing absolute mouse coordinates to the guest (3.1.6 regression)
  • GUI: show the real version of the Guest Additions, not the interface version
  • GUI: when adding a DVD or floppy slot in the VM mass storage settings dialog, don’t attach a random medium but just leave the slot empty
  • GUI: added –seamless and –fullscreen command line switches (bug #4220)
  • GUI: fixed a SEGFAULT under rare circumstances
  • 2D Video acceleration: fixed display issues when working with non 32-bit modes (bugs #6094 & #6208)
  • LsiLogic: Fixed detection of hard disks attached to port 0 when using the drivers from LSI
  • ATA: Fixed sporadic crash with Linux guests when having a hard disk and DVD drive on the same channel (bug #6079)
  • Network: allow to start a VM even if not all network adapters are attached
  • Network: promiscuous mode support for e1000 and simparavirtualized adapters (bug #6519)
  • NAT: fixed ICMP latency (non-Windows hosts only; bug #6427)
  • SCSI: fixed guest crashes under certain circumstances when booting from SCSI devices
  • VBoxManage: fixed modifyvm –natnet default
  • Solaris Hosts: fixed a kernel panic when bridged networking might fail to initialize
  • Solaris Hosts: fixed priority tagged VLAN packets in bridged networking
  • Shared folders: fixed issue with copying read-only files (Linux guests only; bug #4890)
  • Shared folders: renamed the guest kernel module from vboxvfs to vboxsf to make it load on demand by the Linux kernel. Fixes mounting from /etc/fstab in Ubuntu 10.04
  • Shared folders: fixed setuid file permissions (Solaris guests only).
  • Shared folders: fixed deleting directories recursively (Solaris guests only; bug #6513)
  • Guest Additions: support seamless and dynamic resizing on certain older X11 guests (bug #5840)
  • Solaris Additions: fixed OpenGL library dependencies (bug #6435)
  • Keyboard/Mouse emulation: fixed handling of simultaneous mouse/keyboard events under certain circumstances (bug #5375)
  • Mouse emulation: never switch straight back from Explorer to IntelliMouse mode as it confuses the FreeBSD mouse driver (bug #6488)

  • 3D support: fixed Final frame of Compiz animation not updated to the screen (Mac OS X only) (bug #4653)
  • VRDP: allow to bind to localhost only on Mac OS X (bug #5227)
  • Linux hosts: add host USB support for Ubuntu 10.04 and other hosts without the hal daemon or usbfs (bug #6343)
  • webservice: more structs and array fixes in PHP bindings (bug #5657)
