[ovirt-users] Host keeps disconnecting

Hello all I am trying out ovirt 4 on a single host using the hosted engine. All storage is on the same machine, with NFS3 in the middle. Regularly the host disconnects from the engine - although all the VMs continue working happily. I can re-activate it immediately and it will come online happily, I can then manipulate VMs to my hearts content for a few minutes until it disconnects again and I have to re-activate it. First, am I being stupid trying to run this on a single node? Am I obliged to at least break out the storage in to a seperate node/NAS Second, assuming this is technically possible, where should I be looking for clues? ​ vdsm.log <https://drive.google.com/a/klaxoon.com/file/d/0B1WTcLeiwXQ2emhDQURjU25rYm... ​
