Reserve several resource types with constraints

We want 2 nodes and 4 /22 subnets with the following constraints:

  • Nodes are on 2 different clusters of the same site (Hint: use a site with several clusters :-D)
  • Nodes have virtualization capability enabled
  • /22 subnets are on two different /19 subnets
  • 2 subnets belonging to the same /19 subnet are consecutive
 oarsub -I -l /slash_19=2/slash_21=1+'{"virtual"!="none"}'/cluster=2/nodes=1

Lets verify the reservation:
