Comment 2 eberman 2016-07-13 08:53:48 UTC 
created 10 vms (7.1 rhel workstation) on 3.6.8 engine with 1 physical host holding the Vms

after 17 hour up-time i still do not  see any DB related ERROR in the engine log

also:
tried to work with the VMS from the engine web admin -responsive time seems reasonable and same when i tried working with the Vms by console.
