15.3. Configuring Memory Slots Reserved for the Self-Hosted Engine on Additional Hosts
If the Manager virtual machine shuts down or needs to be migrated, there must be enough memory on a self-hosted engine node for the Manager virtual machine to restart on or migrate to it. This memory can be reserved on multiple self-hosted engine nodes by using a scheduling policy. The scheduling policy checks if enough memory to start the Manager virtual machine will remain on the specified number of additional self-hosted engine nodes before starting or migrating any virtual machines. See Creating a Scheduling Policy in the Administration Guide for more information about scheduling policies.
To add more self-hosted engine nodes to the Red Hat Virtualization Manager, see Section 15.4, “Adding Self-Hosted Engine Nodes to the Red Hat Virtualization Manager”.
