VirtualBox 5.0.2

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

VMM: added support for guest crash report MSRs with Hyper-V paravirtualization
VMM: fixed an issue causing artifically high load averages on Linux hosts
VMM: fixed a kernel panic with thread-context hooks caused by incompatible changes made to Linux 4.2 kernels
VMM: fixed a saved state issue with VT-x/AMD-V disabled (5.0 regression; bug #14304)
VMM: fixed VERR_SUPDRV_TSC_DELTA_MEASUREMENT_FAILED Guru Meditations on certain AMD CPUs (5.0 regression; bug #14370)
VMM: fixed a crash while creating a guest core dumps via the VM debug facility (5.0 regression)
VMM: This release has AVX2 passthrough disabled on every host and AVX passthrough disabled for 64-bit VMs on 32-bit hosts. This will be properly fixed in a future 5.0.x maintenance release (see e.g. bug #14262).
GUI: fixed rare hang and crash on VM shutdown/poweroff
GUI: X11: fixed few crashes caused by the Qt alien widgets feature
GUI: X11: fixed various mini-toolbar geometry quirks like positioning, z-order, transiency issues on certain window managers (bug #14257)
GUI: X11: fixed mini-toolbar minimize button issue under certain window managers (bug #14284)
GUI: VM menu actions availability should now be properly updated on full-screen/seamless/scaled mode switches
GUI: disk encryption password validation should be performed when user confirmed the password, not after each entered symbol
GUI: do not change the VM/group selection in the VM Manager to the newly created VM if it was created by another client (e.g. VBoxManage)
GUI: Mac OS X: do not treat 'almost maximized' VM windows as 'maximized', watch for the strict window geometry instead
GUI: improve the quality in scaled mode under some circumstances (5.0 regression; bug #14303)
VBoxManage: do not deny changing the network adapter type at VM runtime (5.0 regression; bug #14308)
VRDP: allow Windows 10 RDP clients (bug #14216)
Audio: fix a possible crash on VM process termination (5.0 regression)
Storage: improved raw disk access on OS X by unmounting any accessed volume before first use and prevent any mount attempt by the host (bug #14219)
3D: basic support for saving/restoring display lists
Drag and drop: fixed guest to host transfers on OS X hosts
Drag and drop: fixed memory leak on Windows guests
Shared Folders: fixed a problem with accessing CIFS shares (bug #14252)
Shared Folders: improved path conversion between hosts and guests with different path separators (bug #14153)
API: skip resetting of immutable media when the VM in saved state is started (bug #13957)
API: fixed method for setting medium IDs which used zero (invalid) UUIDs instead random (valid) UUIDs if no UUIDs were passed (bug #14350)
API: for Windows host fix detection of API client crashes which have a session open
OVF: properly export all VBox features including the setting for paravirtualization (bug #14390)
Mac OS X hosts: El Capitan USB fixes
Windows hosts: fixed crash when opening Windows dialogs from the VM process on Windows 10 (bug #14351)
Windows hosts: fixed host-only adapter creation issues on Windows 10 (bug #14040)
Windows hosts: fixed audio on Windows 10 (bug #14432)
Linux hosts: more fixes for activated SMAP on Linux 3.19 and newer (Broadwell and later; bug #13961)
Linux hosts: check then name space before attaching to a host network interface (bug #13795)
Linux Additions: Linux 4.2 fixes (bug #14227)
Linux Additions: improved the performance of stat() to speed up certain file operations on shared folders
Windows Additions: fixed a potential crash in the WDDM driver with Windows 10 (bug #14190)
Solaris Additions: added support for X.Org Server 1.17
X11 Additions: various seamless mode fixes, including invisible windows under LXDE.
