Can you explain to me in more detail what you mean by this?
Another possibility would be to remove unRAID and install Linux as the base operating system and host all virtual machines and docker containers (Plex, Gitea,...) there. This would eliminate another layer and I could avoid the performance problem.
Well, it's personal and compatibility reasons.
1. Windows 7 is and was for me the best and last really usable operating system from Microsoft. Unfortunately I can't use it with current AMD hardware.
2. Since I can't work with Windows 7 and don't want to work with Windows 8-10, I still want to use the programs I bought and own a license, especially since there is no equivalent or better alternative under Linux.
3. At iTunes I consume and buy content from two different countries. Unfortunately there are a few hurdles concerning the second account and I am forced to outsource the second account to a virtual machine.
4. Some programs are twice as fast as under Windows and my workflow is not interrupted by intrusive advertising, constant, long and multiple restarts or highly nested menu structures.
That may not sound quite comprehensible to someone else, but I would just like to have a solid, lean and high-performance operating system (Linux) on which I can do 85% of my tasks and would like to distribute the remaining 15% to nested virtual machines (Windows, OSX, ...), which I can quickly create, exchange, test with or delete if necessary - together with an easy to use NAS system like unRAID.
