ESX clusters and KVM compute nodes into the cloud. If the cluster or compute node does not appear
on the overview screen, see Adding compute nodes to the cloud (page 104).
Prerequisites
• Minimum required privileges: Infrastructure administrator
• For ESX clusters:
ESX hypervisor hosts are created and configured in a cluster in vCenter Server. For more
information, see VMware vSphere Documentation at VMware.
◦
◦ vCenter Server is registered on the Integrated Tools screen. See Register VMware vCenter
Server (page 82).
• For KVM compute nodes:
Software, storage, and networking are installed and configured on the compute node
hypervisor.
◦
◦ Space is allocated on the physical server where the hypervisor is running for the log files
captured in the /var/log/nova directory.
NOTE: Instances that are not managed by CloudSystem consume resources and may cause
oversubscription. If you plan to activate an ESX cluster or KVM compute node that is already hosting
instances managed by other tools, you should first manually remove these instances using the same
tools that you use to manage the instances. (This action cannot be performed using CloudSystem.)
Procedure 55 Activating a cluster or compute node
1. From the main menu, select Compute Nodes.
2. Select the ESX cluster or KVM compute node you want to activate.
3. Select Actions→Activate.
• If activating an ESX cluster, then skip to step 4.
• If activating a KVM compute node, first complete the steps below, then continue with step
4.
◦ Enter the user name and password for the operating system running on the KVM
compute node. These credentials are defined when the KVM compute node hypervisor
is provisioned.
◦ Enter the Cloud Data Trunk interfaces used to connect network devices to the KVM
compute node. If there are multiple interfaces, separate them with commas. For
example: eth1, eth2. See Networks in CloudSystem Foundation (page 19).
4. Click Activate.
To exit without activating the ESX cluster or KVM compute node, click Cancel.
5. Verify that the ESX cluster or KVM compute node appears in a green active state on the
Compute Nodes overview screen.
NOTE: Do not activate an ESX cluster in more than one cloud.
Deactivate a compute node
Use this procedure to deactivate an ESX cluster or KVM compute node.
