I have installed openNebula on my VM server.
installed MYSQL database and create oneadmin user and give all privileges and create database opennebula.
Then I installed OpenNebula and configure database in its oned.conf file then started all the opennebula services and access opennebula from webUI.
Then created hosts, virtual network, storage (file, image, system), upload OS images into images storage, then create VM templates and start spinning VM, But unfortunately it failed, and throwing below errors.
I have given sudo access to oneadmin user.
