Use Placement Settings in Administration view to configure metrics that determine how virtual machine hosts are rated during virtual machine placement. When you deploy or migrate a virtual machine, you can customize these ratings to address the unique requirements for that virtual machine.
When you deploy or migrate a virtual machine, each available host is assigned a rating of zero through 5 to indicate the host's suitability for hosting that virtual machine. The host rating is based on the virtual machine's hardware and software requirements and anticipated resource usage. The process of evaluating the suitability of hosts for a virtual machine is known as virtual machine placement. For a detailed discussion of host ratings, see How Virtual Machine Manager Rates Hosts (http://go.microsoft.com/fwlink/?LinkId=113698) in the VMM TechNet Library.
How to set placement defaults for virtual machines
In Administration view, in the navigation pane, click General, and then click Placement Settings in the results pane.
In the Actions pane, under Settings, click Modify.
In the Placement Settings dialog box, under Placement goal, select your goal in determining the most suitable host for a virtual machine:
Load balancing—Each host's suitability is rated based on the intent to minimize the processing load on any one host.
Resource maximization—Each host's 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.
- Load balancing—Each host's suitability is rated based on the intent to minimize the processing load on any one host.
Under Resource importance, indicate the relative importance to place on CPU usage, available memory, disk I/O, and network utilization when placing a virtual machine.
