It doesn't happen automatically - you'd have to use the balloon driver to 
shrink one domain and grow another one.  A feature we'd like to see is 
"auto-ballooning" where dom0 will adjust domU memory footprints based on 
their current utilisation.  This is likely to appear at some stage in the 
future...
