Reservations Overview

Reservations in HyLabs refer to a schedule on which cloned VMs of a Gold Master VM will be delivered to end users.

The Reservations page in HyLabs provides the interface for reservation admins and incharge users to create reservations for participants.

Reservation Life Cycle

  • An Example of One-time Course Reservation:

    1. Once a reservation is saved, it is in Not Running state and none of the associated HyLabs users will be able to access the reserved VMs.

    2. Reservation preparation starts one hour before the configured time and its state is changed to the Preparing state.

      1. An On-Demand, temporary, or permanent assignment type of desktop pool will be created with all HyLabs users as clients.

      2. Reserved VMs will not be accessible during Preparing state.

    3. Once the VMs are prepared, the machines go into the Ready state. HyLabs users will not be able to access the reserved VMs until the reservation starts.

    4. Once the reservation time starts, reservation goes into Running state

      1. HyLabs users can now log in, and on connecting will be assigned one of the reserved VMs.

      2. The reserved VMs are given first come first serve basis - if there are less VMs than the number of participants, then users connecting first will get assigned with the VMs until all VMs are consumed and users logging-in after that will not get any VMs.

    5. Once reservation time finishes, reservation gets expired and VMs will be powered off and deleted as per the configuration.
