See [this article](http://theinvisiblethings.blogspot.com/2010/06/disposable-vms.html) for a background on why would one want to use a Disposable VM and what it is.
Opening a file in a Disposable VM (via GUI)
-------------------------------------------
In some AppVM, right click on the file you wish to open in a Disposable VM (in the Nautilus file manager), then choose Scripts -\> Open in Disposable VM. Wait a few seconds and an default application for this file type should appear displaying the file content. This app is running in a whole new VM -- a disposable VM created for the purpose of view this very file. Once you close the viewing application then whole Disposable VM will get destroyed.

Sometimes it is convenient to open a fresh instance of Firefox within a new fresh Disposable VM. This can be easily done by using the Start Menu: just go to Start -\> Disposable VM -\> Firefox and wait a few seconds until a web browser starts. Once you close the viewing application then whole Disposable VM will get destroyed.
