[one-users] VM in UNKNOWN / paused on KVM

[Ionut Popovici]

If u user in production don't use sqlite db it won't work well because 
.. on every db I/O it will lock db not allowing other process to access db.
So if monitoring access the db .. others things like sunstone or any api 
will have to wait for db unlock .. or for sure u can get timeout.
Same thing happened to me to ! So i moved on mysqlbackend.
