Quoting Carlos Martín Sánchez (cmartin at opennebula.org):

> The core sees that you are requesting something specific to cluster

It makes perfect sense.

I thought this was already possible but I must be mistaken with sharing
resources between VDC / oZones. Did Ruben create #2591 for this ?
Thanks for your explanation.
