Ubuntu crashes during runtime or at installation

I have changed my computer (to Win10) and moved my old Ubuntu vm from the old one (Win7) to the new. The VM will start but crashes after a few minutes. Then I have tried to create a new VM (Ubuntu 20.04 LTS) and got a fatal error message. (Log is attached)

Resolution: duplicate

The logs indicate you are actually using the NEM/Hyper-V backend in VirtualBox, we fixed some serious issues lately as discussed in #19695. Please try the latest 6.1 testbuild linked there and see whether your VM starts working again. Closing as a duplicate for now as I'm certainly sure you are affected by one of these issues, please reopen if that happens not to be the case after trying the latest testbuild.
