the image is missing the ‘host’ command, used by the DNS_HOSTNAME variable in the context scripts.
I think this needs to be fixed in upstream, that means at - I don’t know.
It says in the marketplace the image was published by “Admin”
It’s the appliance “Debian 8.4 image for KVM hosts under OpenNebula” with ID 56040c398fb81d7410000006
Also, who is “admin” anyway? I hope someone on the OpenNebula team
