My question is what would be easiest for libvirt:

- "aggregation" attribute only present when driver supports aggregation
  (possibly containing max number of resources to be aggregated)
- "aggregation" attribute always present; contains '1' if driver does
  not support aggregation and 'm' if driver can aggregate 'm' resources
