Hi,

I have a small Vsphere 6.7 environment, without Vcenter, for test purposes with a maximum capacity of 26,4 GHz. The CPU has 8 cores with a clock of 3,3 GHz.

The virtual machines need CPU reservation due to the application that runs on them, and the total reservation for the VM is 24 GHz.

The problem is that I can't power on all the VM's because the system returns me the message that "The available CPU resources in the parent resource pool are insufficient for the operation."

Why does the Vsphere return the error message also if the total reservation doesn't exceed the maximum capacity? I've also read the https://docs.vmware.com/en/VMware-vSphere/6.7/vsphere-esxi-vcenter-server-67-resource-management-gui... guide, but I still don't understand the reason why.

Any suggestion?

Daniele
