Update on this problem (happily now resolved! :) Perusing the oVirt Bugzilla tix, I ran across this one - "failed Activating hosted engine domain during auto-import on NFS”: https://bugzilla.redhat.com/show_bug.cgi?id=1290518 In comments #9 and #12, I got the resolution of my problem: 1) In the System node, Storage sub-tab, alt-click on the Unassigned hosted_storage SD, and choose Destroy, confirm and OK - SD is removed 2) Within a minute, the hosted_storage SD reappears; it is in status “Maintenance” 3) Go to the Data Centers node, Storage sub-tab, click on the hosted_storage SD and click the Activate link 4) Within a few seconds, the hosted_storage SD goes into state Active 5) Within a minute or so, the HostedEngine VM appears in the VMs node, and is in status Up This is the sequence of messages in the Events section for all of this: Jan 6, 2016 9:25:51 PM Hosted Engine VM was imported successfully Jan 6, 2016 9:25:51 PM Starting to import Vm HostedEngine to Data Center Default, Cluster Default Jan 6, 2016 9:25:51 PM Storage Domain hosted_storage (Data Center Default) was activated by admin@internal Jan 6, 2016 9:24:46 PM Storage Domain hosted_storage was updated by admin@internal Jan 6, 2016 9:22:35 PM Hosted Engine storage domain imported successfully Jan 6, 2016 9:22:35 PM Storage Domain hosted_storage was attached to Data Center Default by SYSTEM Jan 6, 2016 9:22:35 PM Failed to activate Storage Domain hosted_storage (Data Center Default) by SYSTEM Jan 6, 2016 9:22:35 PM This Data center compatibility version does not support importing a data domain with its entities (VMs and Templates). The imported domain will be imported without them. Jan 6, 2016 9:22:24 PM The Hosted Engine Storage Domain doesn't exist. It should be imported into the setup.

In 3.6 the hosted engine VM is being imported into it's own DB, but there's no active domain when you start. This is the cause for the noise, and we're working on improving it.

Again, I am running hosted engine on hyperconverged infra. Is this issue possibly related to Bug 1269768<https://bugzilla.redhat.com/show_bug.cgi?id=1269768> ?
