Investigating ESX/ESXi virtual machine resources

Not enough resources to Power On the virtual machine.
There is enough memory in the ESX/ESXi host but it still cannot Power On the virtual machine.

This article helps identify if there are custom configurations set for resources.

To verify the virtual machine is configured with enough resources:

Connect to the ESX/ESXi host directly using VMware Infrastructure/vSphere Client.
Log in as a user with administrator privileges.
Right-click the virtual machine from the Inventory panel and click Edit settings.
Click the Resources tab.
Check if the Memory and CPU reservations are set correctly.
Click OK to save changes and try Powering On the virtual machine.

If the virtual machine is part of a Cluster and Resource Pool configuration:

Connect to the ESX/ESXi host directly using VI/vSphere Client.
Log in as user with administrator privileges.
Right-click on the Resource Pool where the virtual machine is and click Edit settings.
Check if both CPU Resources and Memory Resources are set to the appropriate level to accomodate all the virtual machines.

Note: Check the Resource Management Guide for your version of ESX/ESXi Server or VirtualCenter/vCemter Server.
