We've done some testing of macOS/ARM64 Dev preview (build 7.0.x revision 163780) on MacBook Pro with different CPUs (M1/M2) - On M2 we can confirm that both arm64 and amd64 Linux guests are working, but amd64 has worse performance. - On M1 machine, we couldn't start neither of them (arm64/amd64). (critical error and fails to boot) Do you have any interest in development work of porting to Windows arm64, and would you accept patches for it? If so, could we expect some help, at least in the form of answering questions and giving general guidance? Would the code for macos/arm64 be good starting point for inspiration? There is also this guide https://www.virtualbox.org/wiki/Porting_VirtualBox although in draft state and incomplete. We also did some initial code analysis and understood that a significant amount of work is needed. Some estimate from your side would be helpful, especially if this work would take years.

Aleksey, when did you last try it? I'm not disputing that x86-on-arm even in the latest dev snapshot is painfully slow for fat OSes like Windows 11 or Ubuntu 24.04 (it is much faster than some months ago and overall much more working than the hopeless state of 7.0.x which was very buggy and even worse performance wise). In any case, try ARM virtualization because that's meant to be usable (right now for Linux VMs only). Not the "many years of work" as in the rumor you're spreading. Life is obviously a lot easier for userland-only tools such as fex-emu mentioned by Sérgio.

Virtual Box by design is a x86 virtualization platform.

Our task is to work with opensource community, and setup multiple applications for use on win11 arm64 machines. One of the tasks is to understand the problems and if possible work on build for Windows 11 arm64. We've seen that there is already some effort invested in Darwin arm64, and we wanted to check if there are similar plans for supporting Windows arm64, and if we can somehow help with that work?
