Why was my VM shut down or suspended?

A VM may be automatically shut down or suspended if:

  • The environment was not in use.

    The environment-wide auto-shutdown options shut down or suspend all of the VMs in an environment after a period of inactivity. For more information, see How auto-shutdown works. To check or change the auto-shutdown options for an environment, see Enabling auto-shutdown for an environment.

  • The VM is configured to sleep or shut down after a period of inactivity.

    • If the guest OS power options put the computer to sleep after a period of inactivity, the VM power state in Skytap changes to Suspended.
    • If the guest OS power options automatically shut down the computer, the VM power state in Skytap changes to Powered off.
  • The VM was in use, but it was being used over a published service or public IP connection.

    The environment-wide auto-shutdown options feature doesn’t monitor published services or public IP addresses for user activity in the VMs. For example, auto-shutdown may recognize a VM as inactive, even when it’s being used via RDP or SSH connections over published services.

    To prevent a VM from automatically shutting down or suspending while published services or other unmonitored services are in use, run a script that periodically sends keep-alive messages to Skytap. For instructions, see Sending keep-alive messages from a VM to prevent auto-shutdown.

  • The environment was copied or saved as a template.

    VMs are automatically suspended during these actions. The environment may have been copied or saved by an automated script, schedule, or another user.

To further investigate why a VM was shut down or suspended, view the recent environment activity, or work with a Skytap administrator within your organization to review the Skytap auditing report.
