In this process we already have our basic OS in our opennebula. Now need to create a VM in OpenNebula and install some configuration along with contexturization features of opennebula 1. Create vm on opennebula 2. Install opennebula-context to vm 3. Poweroff vm 4. Save image to other name 5. Upload new image to minio storage 6. Delete vm
