There are instances where Cloud Director will timeout waiting on vCenter whilst performing a "Relocate VM", "import VM", or "Clone" operations.
In those instances, you may see an error such as :
The vCenter Server operation ([vcId=########-###-###-######, moref=task-#####]) has taken too long (28800.00 seconds). VMware Cloud Director considers this operation timed out.
VMware Cloud Director 10.x
This occurs as the task takes way longer than the pre-defined timeouts on Cloud Director.
Resolution involves making modifications to Cloud Director Database. Contact technical support and note this Knowledge Article ID (320498) in the problem description. For more information, see How to Submit a Support Request
Workaround: Determine vCenter task that is causing the delay and perform that task outside Cloud Director, for example if the OrgVDC is using a different Storage Profile that the current VM location, vMotion to the same Storage so that the Cloud Director VM import task is shorter than the timeout.
