Suspend ( ) an active instance to:

  • free up computing resources for other users
  • safely preserve the state of your instance without imaging
  • preserve your resources and quota allocation (SUs are not charged when an instance is suspended)
    • NOTE: Though not currently charged, Memory and Disk are stored and continue to place demand on system resources. 
  • resource usage charts will only reflect the inactive resources when the instance is fully suspended

The instance status will change from " Active" to " Suspended" in the Atmosphere Instances status panel as shown in Figures 1 and 2.

Values and settings stored only in memory will be maintained, as in putting a physical computer to "sleep".

Note
  • The IP addresses will almost certainly change when the instance is resumed, whether it as suspended or shutdown. Configurations and settings may need to be adjusted accordingly.
  • It may take 5-15 minutes (depending on system load) to resume your instance.


Stop (◼︎) an active instance to:

  • free up computing and some storage resources
  • preserve your resources and quota allocation

    • NOTE: Though not currently charged, Disk resources are stored and continue to place demand on system resources.
  • your resource usage charts will only reflect the inactive resources when the instance is fully suspended

The instance status will change from " Active" to " Shutoff" in the Atmosphere Instances status panel (Figures 1 and 2).

Values and settings stored only in memory will be lost, as in shutting down a physical computer.

Shutting down a VM from Linux

If you are going to stop your instance, shut down the VM gracefully and securely. In a GUI environment on Linux, the methods may vary.

Launching a terminal and running the shutdown command as root (or with sudo privileges) should work consistently across Linux versions:

            /sbin/shutdown –h now OR sudo /sbin/shutdown –h now

This will stop all operations, log out other active users on your VM as the system powers down and show your VM as " Shutoff" in Atmosphere once the VM has shut down.


Note that sometimes the Atmosphere interface doesn't update in a timely manner to reflect the true status of the VM. If you have done a shutdown from the console, then do a hard refresh of your browser about a minute after shutdown. This is usually ⌘-R on a Mac and Ctrl-F5 on a PC. Check your browser's documentation to verify.

In general, refresh the browser to verify the VM state if in doubt.


For information on the other options available from the Actions menu see Instance management actions.
