Hello!

Anyone please help me here? I run the 583centos ova go through the auto discovery job, it finds my hosts, then I click on the hosts it found on that job, select common services all completes well, HOWEVER no hosts or services show up because none are imported?

Checked all under admin: engine status all show green but we have this error:
Error: No output from backend!

How is this possible for a brand new VM?

Many thanks!
