Hi,
I found this forum today, and I have to say I enjoyed reading 54 pages of this thread ... long story short, I have managed to install latest DSM update into Virtualbox. I used all known files and experimented with cca 25 iterations until I managed to find the right one. I will play with RAID volumes next, I hope everything will work.
I extend my thanks to all experts on this forum, I hope you will all continue this great work.

Feel free to update, change, improve etc ...
Kind regards,
Mitja
