There is need possibility to group resources for set quotas

Example:¶

Datastores

- I want to group 5 datastores with images type into one datastore.
I want to set quotas to only this datastore, and allow users place images on it.
If free space on this group comes to an end, I will add another one datastore to this group, this action will be transparent for user.

Virtual Networks

- I want to group 10 virtual networks into one.
I want to set quotas to only this virtual network, and set this virtual network for use on my templates.
If free leases on this group comes to an end, I will just add another one virtual network to this group, there is no necessity to update my templates for use new network.

Proposed solution:¶

I think it may be realized using dummy drivers that used now for network reservations: https://docs.opennebula.org/5.4/operation/network_management/manage_vnets.html#virtual-network-self-provisioning-reservations

When creating group of resurce, the new dummy resource will be created, that linked to several another resources.

Workaround for networks:¶

For now I use several virtual networks each with separated subnet and separated VLAN_ID. I found that there is possibility to override network parameters if assign variables like VLAN_ID to address range.
This is working fine, I would like something like this for datastores.
