Environment

• VMware Cloud Director 10.x

Cause

• This issue occurs when the Network Pool quota reached its limit thereby causing the network deployments to fail as part of the vApp/VM power operations. 

Resolution

• To resolve the issue,

1. 1. Increase the network pool quota as per the step 4(c) in Edit the Network Settings of a VMware Cloud Director Organization Virtual Data Center.
   2. Start the vApp/VM again

• If you are still facing the issue after following the above steps and you are using VMware Cloud Director 10.6.1 or lower this is a known issue which is rectified in VMware Cloud Director 10.6.1.1.as per the VMware Cloud Director 10.6.1.1 Release Notes:
  • Powering on a VM fails with a OperationLimitsExceededException
    If you set a custom quota for the maximum number of provisioned networks in the organization VDC backed by a network pool, if a vApp is in Partially Powered Off state, powering on a VM fails with the following error.

  • Unable to deploy network <network-name> because the network quota for this Organization VDC has been reached.
