[17:29] <existence> Hello. I'm new to MAAS/conjure-up but have managed to get some nodes deploying. I'm trying to reduce the amounts of nodes openstack deploys to, and ideally specify which nodes share which services. When using conjure-up to deploy openstack-kvm I see an advanced option for "units" but unsure how changing this affects the deployment or how services are allocated to nodes in MAAS?
