AFAIK, you "cannot"(*) run Virtualbox and virt-manager simultaneously, as they will compete for the control of the hardware (I would love to be wrong on this one...). This is a showstopper if one has many VirtualBox VMs already and only want to run Tails in addition. Need to either be possible to run both, or to find a way to do this on Virtualbox. The ...

The issue is that the disk you created is not attached to VirtualBox as a removable USB drive, which is what Tails (or, more precisely, the live-boot tool that is used by Tails) is looking for.

My bad. Actually, X works. The problem is: it has nothing to do. So it does nothing and closes. I installed lightdm and now I see the login screen as expected. And when I log in, the WM starts.

If you want to configure key based authentication on your remote server you need to actually add your key to it. You can do that using ssh-copy-id which is available on most distributions with the following syntax: ssh-copy-id remote_user@remote_server Note: You will need to know remote_user's password to complete this. It will then look for your id_rsa....

I had this come-up today. In my case, I had selected "Enable EFI" on the Settings: System panel, on the Motherboard tab. That was conscious because the drive I wanted to boot from wasn't (booting). This can be removed by unchecking the check-box. While it looks useful, it is very frustrating so I advise people to open a web page with the help outpur ...

I recently faced the same issue, and after some research I came up with the solution that doesn't require to use VBoxVGA adapter and reinstall Manjaro. The TL;DR version is, you needed to install linux419-headers, not linux419-kernel.
