There are some non-root google play apps(debian noroot <https://github.com/pelya/debian-noroot> by pelya and GNURoot Debian <https://github.com/corbinlc/GNURootDebian> by corbin) that basically provide chroot into another linux system by using proot library. `Chroot`ing is not using a VM but using a boxed system under a regular android(or any unix) system. AFAIK,it runs programs natively but some filesystem and socket operations(or some privileged operations) go through proot(or used chroot library) library to simulate a root system.
