Edge Node VMs have a CPU Reservation that is off by a factor of 1000.

Products

• VMware NSX

Issue/Introduction

The purpose of this KB is to provide how to fix CPU reservation of NSX-T Edge VMs.
Edge Appliance CPU reservation is different than expected on 3.0.0.
For example, when deploying a Large Form Factor Edge Node VM, the vCenter Cluster CPU reservation for the edge appliance is created as 8MHz, where as a reservation of 8,000MHz is expected.

Environment

VMware NSX-T Data Center

Cause

The NSX-T Manager Edge CPU Reservation is incorrectly defined in the OVA:
OVF AllocationUnits are hertz * 10^6
OVF AllocationUnits should be hertz * 10^9

Resolution

This issue is resolved in NSX 3.0.1.

Workaround:
In NSX-T 3.0 and later this reservation is now configurable during Edge Node deployment:

After the deployment:
Increase the CPU reservation by a factor of 1000. A restart of the Edge Appliance is not required.

Additional Information

Impact/Risks:
CPU reservation is different from the expected value.
