Maintenance version of the VirtualBox is released – VirtualBox 3.0.12


VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software. The Virtual Box Team did a┬ámaintenance release “VirtualBox 3.0.12” last week.

The following items were fixed and/or added in this maintenance release:

  • VMM: reduced IO-APIC overhead for 32 bits Windows NT/2000/XP/2003 guests; requires 64 bits support (VT-x only)
  • VMM: fixed double timer interrupt delivery on old Linux kernels using IO-APIC (caused guest time to run at double speed)
  • VMM: reinitialize VT-x and AMD-V after host suspend or hibernate; some BIOSes forget this (Windows hosts only)
  • VMM: fix loading of saved state when RAM preallocation is enabled

  • GUI: never start a VM on a single click into the selector window
  • Serial: reduce the probability of lost bytes if the host end is connected to a raw file
  • VMDK: fix handling of split image variants and fix a 3.0.10 regression
  • VRDP: fixed occasional VRDP server crash
  • Network: even if the virtual network cable was disconnected, some guests were able to send / receive packets
