Error: "Deployment of Virtual Machines in this Organization VDC has been disabled due to insufficient resources" when powering on or editing a VM

Products

• VMware Cloud Director

Issue/Introduction

• Cannot power on any virtual machines in a Pay As You Go (PAYG) Organization VDC in VMware Cloud Director (VCD).
• The following error is visible:
  
  Deployment of Virtual Machines in this Organization VDC has been disabled due to insufficient resources in the Provider VDC. Please contact the System Administrator
   
• Cannot start virtual machines even though resources are sufficient.
• Resource modification disabled on OVDC.
• New VM deployments are blocked.

Environment

VMware Cloud Director

Cause

This issue occurs when users overcommit the resources for a Provider vDC which contains PAYG Org vDCs. Cloud Director disables PAYG operations when 'Total Reservation Sold' exceeds the Available Reservation in the PvDC Resource Pool. 
 
As PAYG Org vDCs use resources from the Provider VDC, it is possible for them to cause contention with the other Organization VDCs and as such are disabled when the PvDC Resources are not managed correctly. The values for 'Total Reservation Sold' (for all vDCs in a given PvDC) should be less than available reservation in the PvDC Resource Pool.
 
Administrators can monitor the Total allocated memory, memory reservation for a Provider VDC. This reflects the total "sold" or committed capacity versus the actual physical capacity of the underlying vSphere clusters.

Resolution

By default, vCD disables all PAYG Power On operations as soon as the overcommitment occurs. To resolve this issue, PAYG operations need to be re-enabled in the database.
