Kịch bản với Microsoft Virtual Server, VMware GSX Server và ESX Server Trong trường hợp người tiêu dùng các phiên bản Microsoft Virtual PC và VMware Workstation đi kèm với điều khiển dòng lệnh, không đơn giản như vậy có sẵn với các sản phẩm ảo hóa máy chủ. Kiểm soát máy chủ ảo hóa là đạt được thông qua người sử dụng giao diện đồ họa hoặc lập trình. | Chapter 25 Scripting with Microsoft Virtual Server VMware GSX Server and ESX Server Where the consumer versions of Microsoft Virtual PC and VMware Workstation come with command line control no such simplicity is available with the virtualization server products. Virtualization server control is achieved through the graphical user-interfaces or programming. There is a lot of sample source code that either comes bundled with the products or is downloadable from the vendor support site however this does not mean that all critical information is covered in detail. VMware provides their sample scripting examples installed with their products and Microsoft has a support site dedicated to scripting Virtual Server. Rather than reiterating what is bundled with the products this chapter is taking a real-world need like performing backups of virtual machines and presents a walk-through on how to accomplish that task with each of the scripting application programming interfaces APIs . Getting Started with Application Programming Interfaces APIs The starting point in writing a script or scripting any application is to find out what language bindings are provided to drive the product s automation facilities. Sometimes it is a built-in scripting language other times it is a static or dynamically loaded native library or a managed programming assembly or interop library like for a Microsoft .NET service. In the case of Microsoft Virtual Server and VMware GSX Server on Windows their scripting interfaces are driven by a Component Object Model COM library that is registered with Windows 589 590 Advanced Server Virtualization upon product installation. For VMware ESX Server its scripting interface is driven by Perl version integration modules. Since both vendors virtualization product APIs on Windows are written in COM they are easily accessible through Visual Basic scripting VBScript. For complex automation and complex data structure manipulation it is necessary to use an .
