I think he means running linux using a vm. Possibly with vagrant for dev/testing purposes. As far a I now there isn't a general purpose vm for android/arm.(There are some javascript x86 emulators with linux and probably something else but I don't know how easy it is to use for developmnt). android by default doesn't have even a minimal linux cmdline toolset although you can install it.
