\section{Wiping VM}
Before starting this section, it should be noted that I don't have a prior low level knownledge of data wiping. 
This section is some thinkings about how can we assure that a file have been deleted. And in our context, the goal would be 
to wipe out a LVM image.

\subsubsection{TL;DR of my understanding of the issue}
Magnetic disk have non physical way of wiping data that are considered as relatively reliable.

SSD are a nightmare to wipe anything, and in most of the cases, it  is impossible.
 
\subsubsection{Things that could by implemented by QubesOS}

TODO.

Links to the ongoing discussion on the subjects.
But basically my idea: encryption, and store the encryption key on a specific physical device that can be logically destroyed (HDD ?), or that can be easily physically destroyed (MicroSD ?)
