Apple now allows Mac virtualisation

Sharp-eyed license readers have found that Leopard Server now allows you to run multiple copies on the same Apple machine via virtualisation. Why is this important? Because virtualisation has been shown to significantly improve certain areas of server performance, reduce costs, and have security benefits. The fact that Leopard can be virtualised will give hardware like Xserve a boost – and provide a good reason for sysadmins to upgrade (previous OS X Server licenses have not allowed it, so if you want virtual Mac servers, you need to buy Leopard.)
