How Should I Read This Chapter¶
This Chapter shows different mechanism available to administrators to control the capacity assigned to Virtual Machines as well as that available to the users:
- First you can control the apparent capacity of Hosts configuring its overcommitment.
- Also you can fine tune the scheduling policies that controls how resources from Hosts, Datastores, and Virtual Networks are allocated to Virtual Machines.
- Similarly, you can limit the resources that are made available to users with the quota system.
- Finally, some workloads may require that you co-allocate or coordinate the capacity assigned to a group of Virtual Machines. Affinity and placement rules can be set for VM groups.
These guides are compatible with all hypervisors.
