Hello everyone,<br>
<br>
keep in mind that the current target of the VirtualBox package for
macOS/ARM (which is an unsupported developer preview at the moment
due to its early state) is actually running VMs with Intel x86 or
x64 instruction set, initially through emulating one instruction
after the other which means it has very modest performance (in less
diplomatic wording one could call it painfully slow). Which
implicitly does not need or benefit from Rosetta in any way.<br>
<br>
Once the basics are working we hope to look into improving
performance, which will be another significant project. The package
for macOS/ARM will remain in unsupported developer preview state for
the foreseeable future.<br>
<br>
To spell it out even more clearly: the target is creating and
running 'regular' Windows for x86/x64, and likewise Linux (and
eventually Solaris, *BSD and other OSes) for x86/x64 in the VMs,
i.e. what you might have done previously on macOS/Intel or other
VirtualBox installs.<br>
<br>
At the moment there is absolutely no way to run VMs using ARM code
in VirtualBox. <br>

<div>Since we'd be running a VM on an ARM OS, we'd only be
interested in translating our user space applications (which
are mostly Inte applications), not kernel space code.</div>
<div>Right now, we cannot use Rosetta within any VM unless we
build the VM using the Apple Virtualization Framework.</div>
<div>I believe that's what UTM solved in their latest version
and was hoping VirtualBox would do something similar.</div>

Rosetta will be very hard (or maybe impossible), because it<br>
works with user-space applications only. It cannot virtualize<br>
drivers/kernel-space code/VMs.<br>
Also Apple may drop Rosetta support like they did for PowerPC

3 years after Intel Macs were announced.<br>
