虚拟化采用了vmware 公司的vsphere产品，版本6.x
使用开源项目：github.com/vmware/govmomi 来实现虚拟机自动化部署流程
虚拟机配置对象是：

}在基于模版克隆时，会设置客户机操作系统，在开发中，工程师将操作系统设置为
代码语言：javascript复制 VirtualMachineGuestOsIdentifierOtherLinux64Guest = VirtualMachineGuestOsIdentifier("otherLinux64Guest")测试后发现使用该操作系统，克隆后的虚拟机无法支持cpu 热插拔特性，在vsphere控制台上查看虚拟机配置，发现CpuHotAddEnabled 单选框没有勾选。
调试：
代码语言：javascript复制types.VirtualMachineConfigSpec{
Name: "test-linux",
GuestId: "centos7_64Guest",
NumCPUs: 4,
MemoryMB: 6,
CpuHotAddEnabled: types.NewBool(true),
MemoryHotAddEnabled: types.NewBool(true),
CpuHotRemoveEnabled: types.NewBool(true),
}由于sdk 结构对象类型采用xml 序列化模式，特将该对象转化打印
代码语言：javascript复制xml, _ := xml.MarshalIndent(虚拟机模版config, " ", " ")xml 处理参考

// considering the element path provided in its tag.

}在对结构体对象进行打印时，可使用%v, % v, %#v 进行对象打印处理
