In past days I have been using Virtual box for trying other distroes and OSes
Due to restrictions in virtual machine drivers i.e NVIDIA cards can't get performance, however minimalistic
chroot jail can overcome this issue.
I even saw YouTube video on embedded systems like phoneix os inside Ubuntu.
The files inside phoneix iso extracted then, added new entry grub menu then ran it on real hardware [Used grub customizer]. I know for sure besides phoneix chrome and bliss os also can be made like that.
anbox works great rather than installing whole os
In future other(s) may ask these question(s) [including me], Exactly what is the best thing to do Virtualization or a single chroot environment to run linux.
