[PVE-User] proxmox serverfarm - how?

hello, 

we want to build an experimental dynamic „datacenter“ in our makerspace (mostly for academic purpose), where the number of nodes online depends on energy availability, heat demand, processing demand, .... , but if i see this right a proxmox cluster needs half of the nodes +1 online to have quorum, i.e. for example we wont be able to start a vm if only two out of 10 nodes are online. 

what‘s the best way to solve this, i.e. what is the most secure/consistent way? 

eg for a cluster of 10 nodes, what about adding 10 virtual proxmox dummy nodes or qdevice instances in another location (so one single physical host online has quorum) instead of tuning node/quorum number in corosync configuration? 

what we want is a „farm“ but not a cluster. but we want centralized management and vm migration. 

regards
roland
