I used to run whonix gateway and workstation in virtualbox on macos. it worked fine.
i migrated to a nested setup under proxmox and now when booting the VMs with VirtualBox 6.1 I end up with a black screen with a x-windows mouse cursor.
I can switch to console and log in, but connection to tor is not established.
I have tried changing display settings. I had been used Videoram of 128MB and have experimented with 16MB and 64MB without change.
I was using VBOXvga previously, but have tried other options and the same result.
Any ideas how to get this going?
