OpenNebula

oneacctd stop

I am trying to use MySQL with Opennebula Watch, but I have problems to connect to the database.
I created a database oneacct in my MySQL server (the documentation says neither whether the database has to be created nor if a specific name has to be used) and have given all privileges on that database to the oneadmin user. I edited the /etc/one/acctd.conf file and added a line like:

:DB: mysql://root:abc123@localhost/opennebula

my system also have 2 vm running.below i logfile error after oneacctd crash:-
