How to install Oracle Virtualbox 6.0, virtualbox extension pack and configure system path so vboxmanage works on the command line. Oracle Virtualbox download. In a recent video in the “Free Software” series, I showed you VirtualBox, which is a free and open source solution to be able to run other operating systems. Changelog for VirtualBox 6.1. This page lists all changes of the VirtualBox 6.1 Downloads. All branches: 6.0 5.2 5.1 5.0 4.3 4.2 4.1 4.0. VirtualBox 6.1.14 (released September 04 2020) This is a maintenance release. The following items were fixed and/or added.
Hi, I'm using a Gentoo Linux VM on a Windows 10 64-bit host.Up to (and including) VirtualBox 6.0.14 it was all good: The VM used the 'VBoxVGA' graphics, 3D acceleration and auto-resize worked without a problem.
With VirtualBox 6.1.0 and the deprecation of the 'VBoxVGA' driver in favor of the 'VMSVGA' driver (and of course switching to that one), the auto-resize stopped to work. Even after updating the guest additions to 6.1.0. I also removed the 'vboxvideo' kernel module from being loaded and added the VMware grahics driver to the guest's kernel config. The current state is that the graphical environment (KDE running atop X) starts up and is stuck at 800x600px. If I use KDE's System Settings to change the resolution, this is executed but the VM is immediatelly reset to 800x600. If I full-screen the VM or resize the VM's window, the guest doesn't adapt to the new screen size as well.
All other VM 'features' (shared clipboard, shared folder with auto-mounting, 3D acceleration) are working perfectly fine.

On the host's VirtualBox, the 'File -> Preferences -> Display -> Maximum Guest Screen Size' is set to 'Automatic' and the scale factor for 'All Monitors' is set to 100%.

Extension Pack is installed.
I attached a zip-file with the following log files (Booting the VM, then using System Settings to resize to 1280x1024, then resizing the VM's window by mouse dragging, then powering off the VM):
VBox.log Log file from VirtualBox itself
dmesg.log Log file from the guest's kernel. Note the two lines saying '[drm:vmw_host_log] *ERROR* Failed to send host log message.'
config.gz Kernel configuration of the kernel running
Xorg.0.log Log file from the guest's X server
virtualbox-guest-additions.log Log file of the 'emerge' process when installing the virtualbox-guest-additions package (to see configuration options and files being installed)
Virtualbox 6.0.12
GuestProperties.txt Output of 'VBoxControl guestproperty enumerate' ran in the guest machineAlso note that the 'VMMDev: Guest Additions capability report' always says 'graphics: no. When the 'vboxvideo' module was loaded, it changed to 'yes'.

The error message is:

may correct this. Make sure that you are not mixing builds of VirtualBox from different sources.

Of course I tried vboxconfig, but no change.

I use Virtualbox for almost 10 years, my oldest VM still in use has been installed in 2011. I have never had the problems with Virtualbox, that I had in the last 2 -3 month since Virtualbox 6.0.14 and Linux 5.3. In that release 3D acceleration stopped working in more than half of my Linux and Windows VMs. I wrote a bug report 2 month ago and provided all info they requested, but no bug-fixes. Now again the problem with Virtualbox 6.1. Is Oracle is loosing it?
