Hi, As you can read in the contextualization guide [1], there are two "levels" of contextualization: - The networking contextualization, to set the IP leased by OpenNebula from the MAC. - And the generic contextualization, that's what the init.sh script is for.
The init.sh script is just an example of the kind of contextualization you can perform, and you should customize that to your needs. You don't need to create new users, or copy any keys if you don't need to. The whole CONTEXT section is optional, the only requirement is to setup the IP from the VM's MAC. About your networking problem, looks like you are trying to access your VM's IP, but the GRAPHICS attribute creates a VNC server in your Host, not your VM. Regards.
