Hello everyone, you will see I just plugged in the PC to start VirtualBox as every day from a Windows 10 Host and it turns out that now the screen is black (Ubuntu 20.04), I have read out there that you have to disable 3D Acceleration and Hyper -V, but in my case I have it disabled forever. Say, that only happens to me in a virtual machine that yesterday worked correctly, the other that I have still works well. What problem can it be?
Thanks all

Re: Black Screen Virtual Box 6.1
You have no shortage of problems with this VM.
For example, allocating RAM that you don't have.
A secondary problem is that you've only allocated 16MB of graphics RAM. This needs to be 64MB or more.
You also seem to be having some kind of driver error with audio input (microphone). I would disable audio input for now, until you can investigate the problem. Often this may be due to an unsigned driver.
A further problem is that your VM's drive is tiny, at only 10GB, and a large chunk of that is probably a swap partition. I hope this doesn't mean that you fell for the "raw disk is faster" ruse, otherwise I don't know why you would have been so reluctant to allocate a reasonable disk size. My disks are 32GB for test VMs, 64GB or 128GB for VMs I intend to use a lot.
A further problem is that the Guest Additions are ancient history: 6.0.0. You should never be sticking with the x.0.0 version of any software. Update VirtualBox on the host first (6.1.18 is out, you are still using 6.1.16). Then update the GAs.
A further problem is that the Extension Pack is not installed on the host. Best do so.
That's probably enough for you to take care of for now.
For example, allocating RAM that you don't have.
You need to free up a whole load of host RAM, or add more RAM to the host. Plus you only allocated one core to the VM, that is not good for most modern OS. Unfortunately your host only has two cores in total so there is no ideal solution for this, but I would go with 2 cores to the VM.00:00:03.113752 Host RAM: 8120MB (7.9GB) total, 1549MB available
