An error message appears stating that the virtual machine fails to power on.

Problem

The virtual machine fails to power on.

Cause

The virtual machine might fail to power on because of insufficient resources or because there are no compatible hosts for the virtual machine.

Solution

If the cluster does not have sufficient resources to power on a single virtual machine or any of the virtual machines in a group power-on attempt, check the resources required by the virtual machine against those available in the cluster or its parent resource pool. If necessary, reduce the reservations of the virtual machine to be powered-on, reduce the reservations of its sibling virtual machines, or increase the resources available in the cluster or its parent resource pool.
