Currently plex86 is an x86/only project. It's possible to take the
idea of a monitor running in it's own space (page tables etc) over
to another architecture, and supplant the SBE control with
a dynamic translation layer. But that's quite a large task.
Too much functionality to jam into one project, if we want
to get it working now.
If your issue is slowing down the software running in the VM,
I'm sure we can do that. There will be support for kicking
plex86 into a pure emulation mode, like bochs. I have some
similar code for debugging now.
