File /var/lib/one/one.db doesn’t exist  
And an error message displayed “ONE\_AUTH file not present”

Check if you have /var/lib/one/.one location. one\_auth file is located there. It happened to me as well, luckily I had a full copy of the /var/lib/one folder and just copied all the files, restarted the opennebula service and the problem was solved.
