早上收到vkernel的邮件，VMWare宣布放弃vRAM License Model，重新采用基于物理CPU的方式来授权使用vshpere。
由此，可以看到基于vRAM这种坑钱的复杂的授权方式经过了一年左右的实践，证明还不是特别适合目前的大多数客户。
Today, VMware announced that they would discontinue vRAM-based licensing for vSphere 5. This will make vSphere licensing once again based off of CPUs in physical hardware.
As you can imagine, this is a dramatic change from this time last year. This update in pricing removes any apparent cost “penalties” for achieving a high VM density. In other words, the higher the VM density, the less hardware a data center will need to purchase, now with no additional vTAX.
大家更喜闻乐见的是便宜简单的授权模式。vsphere由vRAM回归到基于CPU来计算，是否有可能在某一天采用XenServer的基于物理服务器的模型来计算呢？
