18 Virtual machine configuration for compute services
Within CloudSystem Console, you can define "flavors" for the virtual machines deployed to the
cloud. Flavors define the compute resources that can be assigned to each virtual machine. Also
within the Console, you can do a few actions with virtual machine instances, such as restart and
reboot an instance. However, you provision and deploy VMs through the CloudSystem Portal. See
also Cloud service provisioning, deployment, and service management in CloudSystem Portal
(page 116).
About virtual machine instances
Virtual machines instantiated in the CloudSystem Portal or by using the OpenStack API are visible
in the CloudSystem Console. (See Cloud service provisioning and deployment in Enterprise
(page 134).) Virtual machines instantiated in CloudSystem Enterprise are visible in the CloudSystem
Console and the Cloud Service Management Console.
When an instance is launched using the CloudSystem Portal, it is started and available for use.
You can view attributes of the instance on the Instances screen in the CloudSystem Console.
Managing virtual machine instances
From the Instances screen in the in the CloudSystem Console, you can perform the following actions:
• Create an image from a snapshot of an instance. This allows you to capture the attributes of
the running environment of an instance and duplicate it for future use.
• Start an instance, if the instance is Suspended, Paused, or Stopped.
• Reboot an instance either with a soft reboot that restarts the instance software or with a hard
reboot that forces a power cycle. Instances can be rebooted only when their state is Active,
Shutoff, or Resize pending. If necessary, you can change the state in the CloudSystem Portal.
• Delete an instance. Instances can be deleted regardless of their state.
From the Instances tab in the CloudSystem Portal, you can perform additional actions on instances,
including changing the state, editing, and resizing, among others.
Access the CloudSystem Portal by appending /portal to the Foundation appliance URL in your
browser (for example, https://192.0.2.0/portal).
IMPORTANT: Do not use the CloudSystem Console or the CloudSystem Portal to change the state
of virtual machines that were instantiated using the Enterprise Cloud Service Management Console.
CloudSystem Foundation does not propagate changes made to the instance state to CloudSystem
Enterprise. Therefore, if you change instance states in Foundation, and then view the instance state
in Enterprise, the state will differ from what is shown in the CloudSystem Console and Portal.
CloudSystem Console provides a limited set of state change actions. Cloud users have additional
options. See Enterprise Information Library for more information.
Start instance
Use this procedure to start an instance.
Prerequisites
• Minimum required privileges: Infrastructure administrator
• Verify the state of the instance to be started. The instance must have a state of Suspended,
Paused, or Stopped. (Instances in a Shutoff state can be started using the Reboot action. See
Reboot instance (page 109).)
