nova中vmware的一些叫法

我的研究都很业余。

nova中vmware的叫法

host是指vsphere主机

instance是在vsphere中创建的虚拟机实例

node vcenter集群节点

node也指被计算服务所控制的节点

一些动作是没有虚拟机时的操作

例如，spawn 创建虚拟机,但是从代码看，也是用了instance，这地方是用了imageinfo，uuid等信息，

一些是有了虚拟机才能做的，例如destory

一些小问题

#echo 'answer.msg.uuid.altered="I copied it" ' >>./*.vmx

VMHostAdvancedConfiguration

powercli的操作方法是

Set-VMHostAdvancedConfiguration -VMHost 10.23.112.120 -Name Migrate.Enabled -Value 1
