[one-users] Help to implement GetConsoleOutput

[Carlos Martín Sánchez]

Hi,

1st problem:
Extending $VMID is not supported as you said, but might be a good idea to
do it for some attributes. Please open a request at dev.opennebula.org so
we can consider it for future versions.

Meanwhile, I think you can safely edit the deployment file in the vmm
drivers, just before the deployment.

2nd problem:
The VM dir in the front-end is "/var/lib/one/vms/<vm-id>"

The remote vm dir is built with the data in the last history element. For
example, having this VM

<VM>
  <ID>0</ID>
 ...
   <HISTORY_RECORDS>
    <HISTORY>
 ...
      <DS_LOCATION>/var/lib/one//datastores</DS_LOCATION>
      <DS_ID>0</DS_ID>
...
    </HISTORY>
  </HISTORY_RECORDS>
</VM>

the remote vm dir is /var/lib/one//datastores/0/0

Regards
