Troubleshooting Set CPU Resources or Set Memory Resources When the Value Is Too High

You run the Set CPU Resources or Set Memory Resources action and the task fails with an error appearing in the Recent Tasks messages. The reason might be that you entered a value that is greater than the value that your vCenter Server instance supports.

Problem

The Recent Tasks list indicates that a Set CPU Resource or Set Memory Resource action has a state of Failed. When you evaluate the Messages list for the selected task, you see messages similar to the following examples.

If you are working with Set CPU Resources, the information message is similar to the following example, where 1000000000 is the supplied reservation value.

Cause

You submitted the action to change the CPU or memory reservation or limit value to a value greater than the value supported by vCenter Server, or the submitted reservation value is greater than the limit.

Solution
