How to Decrease the CPU and Memory Resources From the Control Domain's Initial factory-default Configuration
This procedure shows how to decrease the CPU and memory resources from the control domain's initial factory-default configuration. You first use CPU DR to decrease the number of cores and then initiate a delayed reconfiguration before you decrease the amount of memory.
The example values are for CPU and memory sizes for a small control domain that has enough resources to run the ldmd daemon and to perform migrations. However, if you want to use the control domain for additional purposes, you can assign a larger number of cores and more memory to the control domain as needed.
