VirtualBox 3.0.12 is now available

VirtualBox 3.0.12 has been released for all platforms. 3.0.12 is a maintenance release.

Changes in VirtualBox 3.0.12 include
  • 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
  • BIOS: ignore unknown shutdown codes instead of causing a guru meditation
  • 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 (E1000)
  • Network: even if the virtual network cable was disconnected, the PCNet card received some spurious packets which might confuse the guest
  • Shared folders: fixed changing case of file names
  • Windows Additions: fix crash in seamless mode
  • Linux Additions: fix writing to files opened in O_APPEND mode
  • Solaris Additions: fix regression in guest additions driver which among other things caused lost guest property updates and periodic error messages being written to the system log
For a complete list of the changes in this release, please take a look at the VirtualBox Changelog.
