vRNI 4.1 Insufficient capacity on each physical CPU

Deploying vRNI 4.1 you might get an error: Insufficient capacity on each physical CPU.

Insufficient capacity on each physical CPU

And it will fail to power on.

Power On Failure

Because the VM can’t be powered on, it will be deleted.

Deploying with ovftool, you’ll get:

Powering on VM: vrni
Task Failed
Error: Task failed on server: Insufficient capacity on each physical CPU.
Error: Reached maximum wait time of 5 minutes when aborting.
Completed with errors

But at least the VM won’t be deleted and you can troubleshoot it.

The reason for the error, is the VM has CPU reservations more than it can handle.

ie: The VM has 8 vCPU’s, with a 20,800Mhz CPU reservation, but my physical ESXi CPU speed is 2.4Ghz.

Physical CPU speed

So, 8 vCPU’s x 2,400Mhz = 19,200Mhz.

If you reduce the CPU reservations to 19,200Mhz, the VM will power on.

Set CPU reservations

The default reservation is set for a CPU of 2.6Ghz.
