A flexVDI infrastructure uses an instance of flexVDI Manager to manage all the its resources of the infrastructure and coordinate the actions of the rest of all the components. This instance can be created and managed with the flexvdi-config tool. A single flexVDI Manager instance manages a full flexVDI cluster with several hosts. Therefor, we will performe the flexVDI manager installation only once during the installation of the first node of the cluster. The rest fo the hosts only need to be registered with the manager; this step is explained later in the Administration Guide.

From this point, you must use your new password for all tasks that require connection to the instance of flexVDI Manager, both from flexVDI Config and from flexVDI Dashboard.
Register the host with flexVDI Manager
Once the Host and flexVDI Manager instance have been configured, you need to register the Hosts so that the flexVDI Manager can start managing its physical resources. This can be done with the flexVDI Config tool, following these steps.
- Select Manager in the main menu.
- Select Register.
- Enter the password for the flexVDI Manager instance you just installed.
- Finally, flexVDI Config will advise updating the SSH keys of the hosts connected to this instance of flexVDI Manager. Do it.
Upgrade the Manager
When a new version of flexVDI Manager is released, you can update your installation with the flexVDI Config tool. The upgrade process preserves all logical objects created on the platform (guests, policies, storage, etc ...), while repeating the installation process would delete the database leaving the platform as new. However, it is advisable to make a backup of the Manager before proceeding with the upgrade process. To perform an update, follow these steps:
- Select Manager in the main menu of flexvdi-config.
- Select Upgrade.
- Enter the current password for your instance of flexVDI Manager.
- Follow the process to download a particular version of flexVDI Manager as described at the beginning of this chapter. Note that flexvdi-config is able to discern if you want to upgrade or downgrade, depending on whether you choose a later or earlier version than the one that is already installed.
- Confirm that you want to continue with the operation.
- Once finished, it will show a message with the outcome.
