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" ]

But that would make a sense in case when one could be possible to specify IP address in 'onetemplate 
instantiate' command.

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.
