Thanks for your input Mark. At the moment all is well again with the host; anyway I'm going to give a long explanation of what I did below and so possible reasons for that situation. There is also feed for developers answers in that ... I cannot connect at the moment to the host to cut and paste in text but I have access to java console and here is a screenshot containing the line you requested (captured now that all is ok and host up and runnign with two VMs): https://docs.google.com/file/d/0BwoPbcrMv8mvdmdIMUxTRVRVUzg/edit?usp=sharing Which fields are expected to be indicators of problems, as I had yesterday?

The story: oVirt is 3.2.1 - create a datacenter of type local_on_host - create a cluster - the ovirtmgmt is intended to be vlan tagged but I forget it... damn... - I add a host (f18) where I prepared network configured with vlan ifcfg-em1 ifcfg-em1.311 - the host deploy completes successfully --> here in my opinion a possible bug because ovirtmgmt is not tagged? - host reboots and apparently all is ok - I can create local_on_host SD and ISO - all is up and running without any VM yet The host is a blade inside an IMS enclosure and I discover that actually I can configure the storage assigned (second disk of the blade) as FC and that there is also multipath for this kind of servers (see the other thread of mine). The optimal would be to deactivate all and redefine the DC as Fibrechannel type but it seems not so easy.... I probably make an error at this point because instead of directly putting host into maintenance I follow these steps in the gui: - expand my DC at the left - expand STORAGE of that DC on the left - select my storage domain (LSTORAGE) on the left On the right pane I select the line of LSTORAGE and in the bottom pane I select the "datacenter" label where I then select the line of my DC. I choose "maintenance" --> what is it supposed I have done this way? Put storage domain in maintenance or DC or what? Is it supposed to be a correct operation what I've done if the DC is Up and this is the only SD I have? Or would it be correct to receive an error from the system? Because I don't receive any error and I see the SD down and host that keeps staying with the status "Preparing to maintenance" I don't remember correctly my steps here, possibly restart of host that is recognized then as unassigned. After that I cannot "force remove" the DC and I cannot remove the cluster or host because it is not in maintenance. After I also reboot the engine service and restart the host, it comes up normally with all the DC with the old config. At this point I can put host in maintenance and force remove the DC I create a new DC with same name but with type FC and ovirtmgmt as vlan tagged and I see that the existing cluster is still present, so I attach it to the new DC (that has the same name as before). I also find that there is my host that seems to automatically be in this cluster. But at this point when I activate it, it comes up but after a few minutes I get the message I posted at the beginning In host details, its network interfaces keep down. Tried different restarts of host. So I decide to put host into maintenance and select into the gui to "reinstall" it. After this all goes well again..
