When you get this message, it means the passwords between oneadmin and serveradmin are not in sync or you have the wrong hash in ~/.one/ files and the oned (pgrep -lf oned) service isn't really connecting to anything to get the username it needs.   "OpenNebula USER name not found, use the ID instead" We […]

However, this can also be due to the oned service not recycling using one stop then one start. When we try this: [oneadmin@opennebula01 ~]$ one stop […]
