Machine blueprints are the complete specification for a virtual, cloud, or physical machine. Blueprints determine a machine's attributes, the manner in which it is provisioned, and its policy and management settings.
Space-Efficient Storage for Virtual Provisioning Space-efficient storage technology eliminates the inefficiencies of traditional storage methods by using only the storage actually required for a machine's operations. Typically, this is only a fraction of the storage actually allocated to machines. vRealize Automation supports two methods of provisioning with space-efficient technology, thin provisioning and FlexClone provisioning.
Choosing a Blueprint Scenario Depending on your environment and the methods of provisioning your fabric administrators have prepared, there are several procedures available to create the blueprint for your needs.
Create a Blueprint for the Basic Workflow A basic workflow blueprint provisions a virtual machine with no guest operating system. You can install the operating system after the machine is provisioned.
Create a Blueprint for Cloning You can use vRealize Automation to provision machines by cloning from a template object created from a Windows or Linux reference machine.
Create a Linked Clone Blueprint If you are working with a vSphere environment, you can provision a space-efficient copy of a virtual machine called a linked clone. Linked clones are based on a snapshot of a VM and use a chain of delta disks to track differences from a parent machine. Linked clones are provisioned quickly, reduce storage cost, and are ideal to use when performance is not a high priority.
Create a Blueprint for Net App FlexClone Provisioning You can use vRealize Automation to provision clone machines using Net App FlexClone technology if you are working with a vSphere integration.
Create a Blueprint for WIM Provisioning You can provision a machine by booting into a WinPE environment and then installing an operating system using a Windows Imaging File Format (WIM) image of an existing Windows reference machine.
Create a Blueprint for Linux Kickstart Provisioning You can provision a machine by booting from an ISO image, then using a kickstart or autoYaSt configuration file and a Linux distribution image to install the operating system on the machine.
Create a Blueprint for SCCM Provisioning You can provision a machine and then pass control to an SCCM task sequence to boot from an ISO image, deploy a Windows operating system, and install the vRealize Automation guest agent.
Troubleshooting Blueprints for Clone and Linked Clone When creating a linked clone or clone blueprint, machine or templates are missing. Using your shared clone blueprint to request machines fails to provision machines.
