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.
sounds encouraging! Is any information when such feature is planned to be
implemented?
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.
seems reasonable
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 a lot for detailed reply and explanations!
JFYI You can easily add new columns to the onevm list command. The following patch adds a new
DESCRIPTION column to the onevm list output:
https://gist.github.com/8f8499704cbee0e5db84
The onevm.yaml can be defined per user in $HOME/.one/onevm.yaml or globally in
/etc/one/cli/onevm.yaml
Hi Daniel,
Thanks for your patch and efforts!
But I wasn't able to archive desired behavior.
I did the following changes:
$ diff /usr/lib/one/ruby/cli/one_helper/onevm_helper.rb{,.orig}
138,141d137
< column :DESCRIPTION, "DESCRIPTION", :size=>12 do |d|
< d["TEMPLATE"]["DESCRIPTION"]
< end
<
143c139
< :TIME, :DESCRIPTION
---
> :TIME
$ cp /etc/one/cli/onevm.yaml ~/.one/
$ diff ~/.one/onevm.yaml /etc/one/cli/onevm.yaml
42,46d41
< :DESCRIPTION:
< :desc: DESCRIPTION
< :size: 20
<
<
57d51
< - :DESCRIPTION
With help of 'onetemplate update' command I added DESCRIPTION parameter
$ onetemplate show 5|grep -i description
DESCRIPTION="description"
and instantiate a VM based on that template.
Although 'onevm show <VMID>' shows the presence of DESCRIPTION parameter 'onevm list' doesn't show
DESCRIPTION column (neither column name nor content).
'one stop' and 'one start' didn't help.
If you have any guess why it is so then please share it.
Regards,
Nikolay.
Cheers

Nikolay.
THANKS FOR YOUR FEEDBACK!

Hi
Why not using the name of the VM for this?.....
The name of the VM I would like to use to put hostname in it and
perhaps use $NAME in
contextualization as e.g.
CONTEXT=[
HOSTNAME="$NAME.domain.org <http://NAME.domain.org>
<http://NAME.domain.org>" ]
But that would make a sense in case when one could be possible to
specify IP address in
'onetemplate instantiate' command.
Also if you want to append any arbitrary data to the VM (at
creation) you can
simply added
to the VM template as:
DESCRIPTION="this is a web server, use 1234 as root password"
This will be stored in the template ans can be queried with the
onevm show command
or in
the Template tab in Sunstone
As far as I understand that will work for a creation of a single VM
but won't if I need to
create a bunch of VMs with help of 'onetemplate instantiate'
command.
Is there any way to modify certain deployed VM's config to add
arbitrary data like e.g.
DESCRIPTION field (something like 'onevm update')?
Moreover, in my opinion it's not convenient to parse the output of
'onevm show'
command when I
need to get a list of all VMs e.g. what have a word "web" in its
description. It would
be more
convenient to have a separate column for that as I wrote before.
But probably to do
that there
is a need to modify DB schema which is not desirable I guess.
Regards,
Nikolay.
Cheers
Ruben

Dear list,
I wonder if there is any way to specify some text as a
description/comment for a
certain VM in
order to be able toquery such info later e.g. during 'onevm
list' command
execution. I
just
don't want to get lost in all my VMs and which one is for
what.
I would like to have something like
$ onevm list
ID USER GROUP NAME STAT UCPU UMEM
HOST TIME
DESCRIPTION
11 oneadmin oneadmin one-11 runn 100 1G <host1> 0d 02h07

12 oneadmin oneadmin one-12 runn 1001G <host1> 0d 02h03
mail-server
13 oneadmin oneadmin one-13 runn 100 1G
<host2> 0d 00h17
development server
