Chapter 8. Memory
This chapter covers memory optimization options for virtualized environments.
8.1. Memory Tuning Tips
To optimize memory performance in a virtualized environment, consider the following:
- Do not allocate more resources to guest than it will use.
- If possible, assign a guest to a single NUMA node, providing that resources are sufficient on that NUMA node. For more information on using NUMA, see Chapter 9, NUMA.
