I have a host machine that has virtualBox installed, and a guest OS virtual machine is created on it.
I want to test installing virtualBox on that guest OS for training purposes, so this means that I'll be installing VirtualBox on a machine that's actually a guest image running using VirtualBox itself. Do you see any problems with this?
Other than the bad performance is completly possible to Install a Virtual Box virtual machine inside another virtual machine.
Due VirtualBox doesnt virtualize Intel VT-X or AMD-V in its virtual machines and the VirtualBox requires those technolgies for run 64 virtual machines, the second Virtual Machine should be of 32 bits.
