Abstract
Techniques are described for priming virtual machines in advance of the user login, thereby effectively distributing the load on the hosting resources over a wider time interval. A portion of VMs in the pool is allocated for priming. This process is initiated from an advisory service, which can analyze data from different sources, including usage history, rules, and location services. A VM is assigned from the pool and started. One or more application storage volumes and/or writable volumes are attached to the VM. A reclaim timer is then started. If no login event is detected for the user prior to the expiration of the reclaim timer, the VM is reclaimed back in to the pool and made available for other users. If the login event for the user is detected before expiration of the reclaim timer, the user returned the primed VM and the reclaim timer is canceled.
