It's somewhat unclear whether or not m2 arm architecture is supported yet for VirtualBox.
I checked downloads and OS X daily said there is a beta version available for download which supports arm but I can't seem to find it.
I also tried compiling latest (as of this post date) from svn but it doesn't seem to take an arm architecture compile flag:
Code: Select all
$ ./configure --target-arch=arm
Checking for environment:
** Cannot determine system!
