> UI exception misleads when the DB failure happens at the time of VM creation.The exception
says the VM creation failed due to insufficient capacity,This is the same message observed
when any of the system resources get exhausted.There should be some other message saying that
the DB was not reachable as we observe the below error message in the management server logs
