Hello Dan, Nevermind. After 2 months I had some time to look at this problem again but didn't remember I put the server in maintenance mode. I put it in maintenance mode to install updates and doublecheck all configuration and apparently I did something wright as it just works now. Kind regards. 2014-08-28 16:34 GMT+02:00 Andy Michielsen <andy.michielsen@gmail.com>:

Hello Dan,

I can't find a clue in the engine.log but I'm unable to start any VM on this host. Looks like it lost its connection to its datadomain entirely.

Kind regards.

does engine.log have any clues regarding the falure to find a valid host? Do you have guess (are they all operational? are they over-worked?
