How to "wrap" your web application in virtual machine format?

Question

linux

Now many web applications are distributed as virtual machine files (eg *.ovf, *.ova for VirtualBox). The client downloads the virtual machine file, adds it to the hypervisor, launches it, and can work with the web application at the IP address assigned to the virtual machine.

Question: is there a detailed description somewhere on how to "roll up" a web application in such a format?
Or any thoughts on this?

1) Take a virtual machine
2) Install a system on it
3) Set up a web application
