Error: "Total memory required for all VMs in the VRP including current VM(s) being deployed [<value>MB] is greater than VRP maxResourceValue 0MB." occurs when powering on VMs

Products

• VMware Cloud Director

Issue/Introduction

• VMs fail to power on and the error "Total memory required for all VMs in the VRP including current VM(s) being deployed [<value>MB] is greater than VRP maxResourceValue 0MB." is observed.
• The VMs Org VDC uses the Flex Allocation Model.
• Prior to upgrade to Cloud Director 10.6.1 the VMs could power on successfully.

Environment

VMware Cloud Director 10.6.1

Cause

In older releases prior to Cloud Director 10.6.1, the product incorrectly allowed power-on of VMs in a FLEX VDC configured with non-zero CPU/memory allocation and zero CPU/memory guarantee. This behavior was determined to be incorrect. This fault was fixed in Cloud Director 10.6.1. As a consequence, any environment which had previously been utilizing the incorrect behavior will experience this error post upgrade to 10.6.1.

This matter is documented in the Cloud Director 10.6.1 release notes as a resolved issue.

Resolution

To resolve this issue reconfigure the allocation settings of the Org VDC.

With this change in 10.6.1, when CPU/Memory allocation is set to 0 and CPU/Memory resources guaranteed is also 0, then the VM power-on with set guarantee will succeed. Alternatively, if you set a specific non-zero allocation value for CPU/Memory, then then you also must specify a non-zero CPU/Memory resources guaranteed value, such as 20% for example.
