Now we are attending HPDC'11 held in San Jose. In the VTDC'11 workshop, Takahiro presented our reactive VM packing system exploiting postcopy live migration.
By using postcopy live migration, the packing system quickly optimizes VM locations in response to server load changes. It assures performance criteria of VMs in a higher degree than that of using precopy live migration. See more information at http://www.grid-appliance.org/wiki/index.php/VTDC11 .
