Embodiment Construction

[0024] figure 1 is a diagram of a sample computer system with pre-installed software. The example computer system 100 has an operating system 102 and two applications 104 and 106 installed. The operating system 102 may have hardware drivers 108 that the operating system 102 uses to communicate with hardware devices. One such hardware device may be storage device 110 . Storage device 110 may be any type of memory, memory storage device, or combination of different types of memory or memory storage devices, including but not limited to: random access memory (RAM), read only memory (ROM), hard disk, optical disk, digital video disk (DVD), compact disc read-only memory (CD-ROM), etc.

[0025] Storage device 110 may contain operating system files 112 and one or more application files 114 and 116 . Some of operating system files 112 may be executable binaries. When the computer system 100 boots or begins to execute instructions, the executable binary code can be loaded from the...

Abstract

A computing device configures virtual machines using configuration commands. Each of the virtual machines may boot from a corresponding virtual machine image file. As a virtual machine boots or executes, the virtual machine may read from or write to application and operating system files included in the corresponding virtual machine image file. Prior to the virtual machine booting, the computing device may get or set configuration properties of the operating system and applications to be booted in a respective virtual machine by reading from or writing to the application and operating system files included in the corresponding virtual machine image file. The computing device may execute configuration commands to get or set the configuration properties of the operating system and the applications.

Description

technical field [0001] The field of the invention relates generally to software configuration. In particular, the invention relates to the configuration of virtual machines. Background technique [0002] Properly configuring an application can be a laborious and time-consuming manual process. Properly configuring an application may require a human to use a graphical user interface (GUI) to make configuration settings, where slight errors can cause the application to malfunction. The configuration of some applications is very complex because the application may include multiple tiers. A hierarchy can be defined as a group of one or more servers that perform similar functions. For example, a two-tier application may include configuring a web server and a database server. A three-tier application may include configuring a web server, an application server, and a database server. Each tier can include multiple machines to handle load balancing and machine failover.
