This is going to be a short little post about VirtualBox crash when setting up Ubuntu virtual machine.
When I was installing VirtualBox 6.1 and downloaded the latest Ubuntu version (for me 20.04.1 LTS) and was setting up the virtual machine, VirtualBox crashed on boot.
I could not figure out from the crashlog what was actually going wrong until I made a search on Google. The solution ended up be disable audio in the virtual machine settings. I do not care for audio, since I am going to use it for work and music I always use the host machine for anyway.
