[one-users] VM description/comment

Thu Oct 18 13:34:14 PDT 2012

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...

THANKS FOR YOUR FEEDBACK!
