VirtualBox 5.1 Beta 1 released

Postby frank » 3. Jun 2016, 20:05

Please do NOT use this VirtualBox Beta release on production machines. A VirtualBox Beta release should be considered a bleeding-edge release meant for early evaluation and testing purposes.

You can download the binaries here. Please use sha256sum to compare the hash of the downloaded package with the corresponding hash from this list.

Please do NOT open bug reports at http://www.virtualbox.org/wiki/Bugtracker but use our VirtualBox Beta Feedback forum to report any problems with the Beta. Please concentrate on reporting regressions since VirtualBox 5.0.20.

VirtualBox 5.1 will be a new minor release. Here is an incomplete list of changes:
  • VMM: new APIC and I/O APIC implementations that result in significantly improved performance in certain situations (for example with networking, bug #15295)
  • VMM: added support for Hyper-V paravirtualized debugging of Windows guests
  • VMM: emulate even more MMIO and shadow pagetable exits without going back to user mode
  • GUI: overall migration to Qt5
  • GUI: passive API event listener improving the VM GUI performance and response time
  • better support for Python 3
In addition, the following items were fixed and/or added:
  • VMM: many fixes
  • GUI: the Detach UI action is now a part of the VM Machine menu
  • GUI: reworked session information window
  • GUI: the new VM wizard now allows to choose the VM location for the VM which is being created
  • GUI: various bugfixes and internal cleanup
  • Storage: use fallocate or similar if present to speed up creating fixed-sized disk images
  • Storage: implemented NVMHCI-compatible storage controller
  • EFI: many improvements, for example allow to boot from USB
  • OVF: improved handling of signed manifests
  • Windows hosts: rework COM proxy (e.g. bug #8298)
  • Linux installers: no longer rely on DKMS for module rebuilding
