If you look on the ArcaNoae website, they seem to be adamant about supporting ArcaOS on a physical machine *and* in a VM (at least in terms of voicing that support on the webpages). You have a choice, and I hope they continue to support both approaches *equally* into the future:
- every advancement in device drivers, app dev, plugs a current hole
- continued Guest Additions dev keeps ArcaOS entirely problem-free
This is an important point, because you can run ArcaOS on a physical box as the primary OS, which does open yourself up to the problems with that approach ... lack of device drivers, applications that aren't quite modern enough, etc. UEFI allows you to multi-boot your way out of this. Or, ...
Run ArcaOS in a VM, with the HostOS providing *everything* that ArcaOS can't, or may not get to until future releases. There are no major device driver problems, no lack of access to modern apps, and so on.
If you go the AToF path of virtualization (shameless plug, see virtualization sub-forum), then you also get x64 app access within ArcaOS, and more. Everything available at once, no multi-booting.
A (more) modern version of OS/2, and more choices for each on how to run it.
That's progress ... and why OS/2 (ArcaOS 5.1) is still relevant today!
