How to Customize Host Ratings for a Virtual Machine
Use the following procedure to customize host ratings for a virtual machine when you deploy or migrate the virtual machine. These settings override the systemwide placement defaults that are set through placement settings in Administration view.

To customize host ratings for a virtual machine
On the Select Virtual Machine Host page of the wizard, click Customize Ratings.
Under Placement goals, select your goal in determining the most suitable host for the virtual machine:
- Load balancing—Host suitability is rated based on the intent to minimize the processing load on any one host.
- Resource maximization—Host suitability is rated based on the intent to consolidate multiple low-utilization workloads on a single host. Virtual machine placement in these cases involves determining the capacity limits for a particular host and placing virtual machines on that host until the limits are reached.
Under Resource importance, indicate the relative importance to place on CPU utilization, available memory, disk I/O, and network utilization when placing the current virtual machine.
