VM Reservation Fails Because of CPU Limitation

Symptom:

A reservation fails when more virtual CPUs are requested than VMware allows for the ESX server chosen. Messages like the following are displayed:

Virtual machine requires X CPUs to operate, but the host hardware only provides X.

This virtual machine is configured with an unsupported number of virtual CPUs.

Solution:

You can reduce the number of virtual CPUs for the ESX servers in your environment by changing a configuration setting. See the field Virtual CPU Limit in the topic Set Limits on Virtual Machine Resources.
