[ovirt-users] Self-hosted engine: Host cannot activate

I am attempting to install oVirt 3.6 on a CentOS7 host. it is a single server, so I am trying to install a self-hosted engine. I am able to install oVirt 3.5 self-hosted engine, but am having some problems doing it with 3.6. Everything appears to go fine; the engine-setup completes successfully. On the host, I pressed"1" to indicate engine-setup was complete, and it can connect to the webadmin but the host never becomes operational. I am able to log in to the webadmin, and indeed the host is in a non-operational state. When I click on the host then click on the "Virtual networks" tab, all my interfaces are showing a red arrow. When I click on "Setup Host Networks", my "ovirtmgmt" network is unassigned. Believing this to be why my host is not operational (since it is under "Required"), I assigned it to my management interface, but the interfaces still remain red. In addition, the "ovirtmgmt" network does have a green arrow, but also the icon indicating "Out of sync". If I click on "Sync All Networks", I get the following error: "Error while executing action SyncAllHostNetworks: Network is currently being used" which makes sense, since "ovirtmgmt" is assigned/in use. I am unable to unassign ovirtmgmt. Current status is this: - All network interfaces are showing the red "down" arrow - "ovirtmgmt" is assigned to my management NIC, but indicating that it is out of sync - I am unable to unassign the "ovirtmgmt" network (or at least, if I do, the "OK" button is greyed out) I could destroy the engine VM and go through the setup again, with the idea of once it is installed and waiting for the host to become operational, I could do a "Sync All Networks" and see if the networks turn green and go from there. I wanted to see what sort of insight I could get from here first. I am not sure what logs would be useful to you, so let me know what you want to see and I and make them available (I will likely zip them up and post a link) Something else I could try if this becomes a "puzzler" is to do a 3.5.x self-hosted engine then perform an in-place upgrade to 3.6 and see if that works? I would rather try to help make a direct 3.6 install work, though... Thanks, in advance! :-) Regards, Alan
