In most respects, your VM behaves just the same as a real machine 
would - the main differences are the I/O etc. So, just like a real 
machine, your virtual machine will have the same disk contents after 
a reboot unless you do something to damage the filesystems (like not 
shutting down cleanly). If you were to "xm destroy" a guest then that 
would be the equivalent of yanking the power cord on a real machine 
and clearly you may damage your filsystems.
