Root Cause

  • If virt-who mapping shows that the hypervisor names are same e.g.
       {
            "hypervisorId": {
                "hypervisorId": "<uuid>"
            }, 
            "name": "localhost", 
            "guestIds": [
                {
                    "guestId": "<uuid>", 
                    "state": 5, 
                    "attributes": {
                        "active": 0, 
                        "virtWhoType": "esx"
                    }
                },##guests object truncated 
            ], 
            "facts": {
                "hypervisor.type": "VMware ESXi", 
                "cpu.cpu_socket(s)": "2", 
                "hypervisor.cluster": "Public", 
                "hypervisor.version": "6.0.0"
            }
        }, 
	{
            "hypervisorId": {
                "hypervisorId": "<uuid>"
            }, 
            "name": "localhost", 
            "guestIds": [
                {
                    "guestId": "<uuid>", 
                    "state": 1, 
                    "attributes": {
                        "active": 1, 
                        "virtWhoType": "esx"
                    }
                }##guests object truncated 
            ], 
            "facts": {
                "hypervisor.type": "VMware ESXi", 
                "cpu.cpu_socket(s)": "2", 
                "hypervisor.cluster": "Shared",
                 "hypervisor.version": "6.0.0"
            }
        }
  • Above mapping shows all the hypervisor have same name i.e. locahost. Due to the same name, Satellite is not allowing to create a new record hence reporting the validation error.
  • Currently in Sat 6.3 changing the hypervisor_id=uuid in virt-who config is not forcing Satellite to register the systems to use the virt-who- names

Diagnostic Steps

  • On the webUI, check for the task with the label Actions::Katello::Host::HypervisorsUpdate, it fails with below error/trace
