The biggest news in VirtualBox 6.1.16 is the implementation of support for the latest and greatest Linux 5.9 kernel series. This support is offered for both Linux hosts and guests, which means that you???ll now be able to install VirtualBox on distributions powered by Linux 5.9, as well as to run distros that use Linux 5.9 as virtual machines. But wait, there are even more Linux improvements in VirtualBox 6.1.16. For example, this release comes with a workaround to improve the resizing of 32-bit virtual machines that use the VMSVGA graphics controller while avoiding the use of RandR 1.3 due to bugs causing hangs with the X server, as well as VMSVGA 3D support for Linux guests when using the Hyper-V hypervisor.
