[one-users] Opennebula disk throttling.

[Ruben S. Montero]

There are a couple of issues to ease the edition of VM instances to allow
for example adding new parameters to VM virtual hw, or virtual disks in
"not-running" states...

You can always edit the database, of course. Just stop oned, look for
active VMs (VM STATE 3) and update the body column. It is a XML document so
it should be fairly easy to add the attribute to the DISK entities.

After that you need to power-off powe-on the VMs; so the deployment file
with the new attributes are generated.

Cheers
