[Fedora-xen] Cannot erase unsuccessfully created guests

[Marcel Damásio]

Hi Gastón,

First, these 512 of mem are just reserved to xen0 if when it starts. So, you
don't have this memory problem.

And the option 'xm destroy' is just to shutdown a cracked VM (I'm almost
sure).
To erase the VM you need to do 'xm delete'.

Hope I helped.
