How to Use Tails OS on Virtualbox

It's worked. Thanks!!

how can i scale screen of tails

The "connect to Tor" button is not available to me either. I believe it is because I cannot use Tails full screen. Very frustrating. I have Kali, Ubunutu, and Linux Mint on VirtualBox all full screen with no problem. Guest additions is installed. There may be a bug with the current version of tails. I wonder if its possible to download a previous version that does not have this bug?

If you don’t create a disk image does that mean you will have to update every time you use the VM?
