Virtual Machine Lifecycle Control

(cont.)

•

VM lifecycle controlled by:

–

Programmatically (Job / JDL)

–

Manually (through mgmt. console)

–

Automatically on demand

A job makes request for unavailable resource… Suitable VM image is

located, host is located, image is provisioned, instance is initially reserved

for calling job, logic is invoked to make use of new resource

•

VM host/instance selection/placement is similar to

resource selection:

–

Governed by policies, priorities, queues and ranking

•

Provisioning Adapters provide VM abstraction:

–

Special ‘provisioning’ jobs perform operations for each

integration with different VM technologies

–

The provisioning adapter is a JOB!
