I am not a developer but out of personal need, I created a MultiOS GUI for Qemu (Emulator and Virtualiser), all this was possible thanks to the automated scripts created with the freeware programme AutoIt v3.
Through the GUI it is possible to create Virtual HardDisks (HardFiles), install or boot the Operating Systems, AROS, AMiGA OS4.1, MorpOS and MAC OS by simply clicking on the appropriate GUI Icon.
I enclose a small Video showing the booting of the 4 mentioned OS, the systems are not very fast because I used an old DualCore PC with Win7 64Bit, to make the video shorter for some OS I eliminated the system startup waiting time.
