Hello everyone,
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.
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.
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.
At the moment there is absolutely no way to run VMs using ARM code in
VirtualBox.

Thanks Alexey,
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.
Right now, we cannot use Rosetta within any VM unless we build the VM
using the Apple Virtualization Framework.
I believe that's what UTM solved in their latest version and was
hoping VirtualBox would do something similar.

supporting Rosetta will be very hard (or maybe impossible), because it
works with user-space applications only. It cannot virtualize
drivers/kernel-space code/VMs.
Also Apple may drop Rosetta support like they did for PowerPC Rosetta
3 years after Intel Macs were announced.
