User friendliness is essential for the success of the FreedomBox. I
think virtualization is helpful with this respect. On my blog i
described how to build a WordPress virtual machine. One visitor asked me
the following question:
Just curious: Have you considered automating a process like this using
Puppet or another configuration management system, if that’s possible?
It would be nice if a setup like this were as easily built-up and torn
down as a single “app” on a freedombox
One of the reasons i house my modules inside LXC containers is ease of
deployment. If you build a container for one processor architecture it
can be copy-pasted to any machine with the same architecture. For the
configuration and data inside a container i am planning a simple data
interface. As you can see from the WordPress module, there is very
little configuration data that must come from outside the container.
To answer your question: My FreedomBox modules should be built by
competent sysadmins and deployed with the normal Debian package
management tools (hidden behind a nice user interface).

Yes. Cloud companies are very security aware. CPU virtualization
features are mostly there to improve performance, not security. The
hardware of the FreedomBox is not crippled hardware. It is modest
hardware for modest tasks. Cloud companies have more powerful hardware,
but on this hardware they are running far more VM's. From my own
experience i would say that a VM on my FreedomBox has roughly the same
performance as a cloud VM.

Diaspora is just an example. The problem here is that in order to mature
some programs that we want to have on our FreedomBoxes need our platform
