[one-users] Contextualization

Hi Christophe,
I would simply register the context package as a "Context" File in the
"Files & Kernels" datastores. Then update the template of the VM and select
that file in the Context -> Files tab. After instantiating the VM again,
you simply open or mount the cdrom (typically under /dev/sr0) and access
the context package there.
http://docs.opennebula.org/4.4/user/references/template.html#template-context
http://docs.opennebula.org/4.4/user/virtual_resource_management/img_guide.html#how-to-use-file-images-in-virtual-machines
BTW, at some point we want to provide a CD-ROM iso with all the context
packages inside of it, which would come in handy in this type of situations.
cheers,
Jaime
