Hi Ricardo + Nikolay You are right, one thing we have in our short roadmap is to add a generic metada section for VMs. This metadata could be updated using the *update* functionality currently present for other commands.
Just to give you the rationale behind not having this yet. As you probably know the VM template is extended once the VM created with control data (e.g. DISK_ID's, specifric LEASES, SOURCE for DISK...) for obvious reasons we do not want a user to modify this. So we will split this in two, one for the control data and other to be used/modified by the user. For now, as Nikolay suggests this limit somehow part of the out-of-the-box functionality (e.g. adding DESCRIPTION in a bulk submission), this functionality will need a custom program using OCA. About parsing the out put of onevm show, note that you can always get the full pool information with onevm list -x (TEMPLATE included) the onevm list command just parse and pick some of this info and present it in a tabular form...
