Environment

VMware Cloud Foundation 2.3.x
VMware Cloud Foundation 2.2.x

Cause

The "vCenter: Configure Host"  task  will creates  DNS  records for the new workload domain esxi hosts and it will restart  the DNS service, but the task might resume before the DNS service is fully started. This will result in a name resolution failure for the new hosts and the workload domain creation workflow will fail. 

Resolution

This is known issue affecting VMware Cloud Foundation 2.2.x and 2.3.x.This issue is resolved in  VMware Cloud Foundation 3.0.

Workaround:
To workaround this issue, click the Restart button for the failed workflow. The task will continue without any intervention as the DNS service will be up and running.
