Configuring the KVM-FT Hypervisor

After installing the KVM-FT hypervisor (Installing Stratus Cloud Availability Services on KVM Compute Nodes), configure the hypervisors by adding each compute node to a KVM-FT pair group.

To set a KVM-FT hypervisor pair group:

1. In the main menu of Stratus Cloud Workload Services, click Hypervisors to display the Hypervisors page.
2. On the Hypervisors page, locate the first pair of KVM-FT hypervisors, or compute nodes, that you want to configure as a KVM-FT pair group.
3. Click the first KVM-FT hypervisor that you want to add to the pair group. In the option buttons, click to display the Edit Hypervisor panel.

4. In the Edit Hypervisor panel, scroll down to Service Level Definitions, and specify the following tags:

   • Availability Level: Select Mission Critical.
   • Hypervisor Type: Select KVM-FT.

   • FT Pair Group: If this is your first KVM-FT pair group, select Default Pair Group. If you are adding another pair group, select a different pair group name. (You can add pair group names as described below under To add more KVM-FT pair groups.)

     Note: The FT Pair Group field displays only when the selected hypervisor type is KVM-FT.
   • Hypervisor Instance Storage Type: Select the storage type for the hypervisor.
   • Location: Select one or more deployment locations for the hypervisor.
5. Complete any other fields as needed, and then click Save.
6. Repeat steps 3-5 to add the second KVM-FT hypervisor to the same KVM-FT pair group.

7. Ensure that you have installed the two quorum servers required by the KVM-FT hypervisor, as described in Installing Quorum Servers for Stratus Cloud Availability Services.

   Caution: The quorum servers must be installed and running before you deploy your first KVM-FT application.
8. Create a test application to verify that your KVM-FT configuration is functioning properly. For an example that summarizes the process of creating an application, from configuring network connections to creating and deploying a service catalog application, see How to Deploy an Application.
9. Before deploying any KVM-FT applications for production use, optionally configure your KVM-FT hypervisors and Ethernet switches to increase performance, as described in Improving the Performance of Stratus Cloud Availability Services.

To add more KVM-FT pair groups (if applicable):

1. Ensure that you have connected the KVM-FT A-links and installed the KVM-FT software on the compute nodes.
2. In the main menu of Stratus Cloud Workload Services, select Service Level Definitions to display the Service Level Definitions page.
3. On the Service Level Definitions page, click Add Tag in the upper right corner of the page to display the Create New Tag panel.
4. In the Create New Tag panel, complete the following:
   • Name: Type a name for the new pair group. This name displays on the Service Level Definitions page.
   • Standard Name: Type a standard name for the new tag. This tag name gets propagated through the back end.
   • Nest Tag Under: Select FT Pair Group.
   • Description: Type descriptive information about the new tag. Information added here displays at the right of the tag name in the listing on the Service Level Definitions page.
5. Click Create.
6. Repeat steps 1-5 to create additional pair groups, if applicable.
7. To add compute nodes to each new pair group, repeat the procedure above To set a KVM-FT hypervisor pair group.
