VirtualBox 5.0.22

virtualbox

VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.

Some of the features of VirtualBox are:

Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for VirtualBox.
Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.

VirtualBox 5.0.22 is a maintenance release. The following items were fixed and/or added:

VMM: fixes for certain Intel Atom hosts (bug #14915)
VMM: properly restore the complete FPU state for 32-bit guests on 64-bit hosts on Intel Sandy Bridge and Ivy Bridge CPUs
VMM: new I/O-APIC implementation fixing several bugs and improving the performance under certain conditions (bug #15295 and others)
VMM: fixed a potential Linux guest panic on AMD hosts
VMM: fixed a potential hang with 32-bit EFI guests on Intel CPUs (VT-x without unrestricted guest execution)
GUI: don't allow to start subsequent separate VM instances
GUI: raised upper limit for video capture screen resolution (bug #15432)
GUI: warn if the VM has less than 128MB VRAM configured and 3D enabled
Main: when monitoring DNS configuration changes on Windows hosts avoid false positives from competing DHCP renewals. This should fix NAT link flaps when host has multiple DHCP configured interfaces, in particular when the host uses OpnVPN.
Main: properly display an error message if the VRDE server cannot be enabled at runtime, for example because another service is using the same port
NAT: Initialize guest address guess for wildcard port-forwarding rules with default guest address (bug #15412)
VGA: fix for a problem which made certain legacy guests crash under certain conditions (bug #14811)
ACPI: properly notify the guest if the ACPI battery state changed
OVF: fixed import problems for some appliances using an AHCI controller created by 3rd party applications
SDK: reduced memory usage in the webservice Java bindings
Windows hosts: fixed performance regresson with SMP guests (5.0 regression)
Windows hosts: fixes for the shared clipboard
Windows hosts: Windows hardening fix
Windows Additions: fixes to retain the guest display layout when resizing or disabling the guest monitors
Linux hosts: EL 6.8 fix (bug #15411)
Linux hosts: Linux 4.7 fix (bug #15459)
Linux Additions: Linux 4.7 fixes (bug #15444)
Linux Additions: fix for certain 32-bit guests (5.0.18 regression; bug #15320)
Linux Additions: fixed mouse pointer offset (5.0.18 regression; bug #15324)
Linux Additions: made old X.Org releases work again with kernels 3.11 and later (5.0.18 regression; bug #15319)
Linux Additions: fixed X.Org crash after hard guest reset (5.0.18 regression; bug #15354)
Linux Additions: don't stop the X11 setup if loading the shared folders module fails (5.0.18 regression)
Linux Additions: don't complain if the Drag and Drop service is not available on the host
Solaris Additions: added support for X.org 1.18
