A couple of days ago all was working fine on my macOS 10.15.5 with VirtualBox 6.0.20.

VirtualBox 6.1.20 released! Oracle today released a 6.1 maintenance release which improves stability and fixes regressions. Sigil. See the Changelog for details. New January 19th, 2021 VirtualBox 6.1.18 released! Oracle today released a 6.1 maintenance release which improves stability and fixes regressions. See the Changelog for details.

1. For Mac OS X hosts, Oracle VirtualBox ships in a disk image ( dmg ) file. Perform the following steps: Double-click on that file to have its contents mounted.
2. One of the systems got a kernel panic again. The system was macOS 10.14.5 and Virtualbox 6.0.4. It seems that VirtualBox is not compatible with macOS 10.14.5. Please excuse the inaccuracy of my error messages, the reason is the almost simultaneous update of macOS 10.14.5 and VirtualBox 6.0.8.

I have Windows10 and Ubuntu. Today I needed Windows and when started I got the Windows 'blue' screen saying that some critical system files were not found and it tried to repair itself, for no avail.
Then I tried Ubuntu, which simply didn't start and its status turned to 'Aborted'
Making a long story short. I did a clean install of VirtualBox 6.1.10, used new and backed up VDI files for Windows and Linux. Created new VM re-using my VDI disks and tested, trying to look at the logs.
It simply getting aborted whatever I try. I have no idea of what's going on. Looking at my log at

, the only things I found suspicious were:

I can run Ubuntu memory test from the Grub option and starting the VM in headless mode the status shows 'running' and that's all.
