Could you test this please? @onion_knight
After installing Whonix host operating system - #189 by Patrick and grub-live package.
If not a too personal privacy intrusive a question, how much host RAM can you test this with? 4 GB, 8 GB, 16 GB, 32 GB? Does booting into live mode work and are VMs still startable? Multiple VMs?
Is there a difference Whonix-Host ISO Live vs Whonix-Host installed Live?
