DRS Host affinity using generalized rules (not specific vm names)

Hello All,

I am implementing a Horizon 7 solution for a customer on a 7-node Nutanix cluster using automated VM generation (VMWare composer).

Due to some of the client software licensing (not VMware), I am limited to running the agent VMs on only 2 hosts (license limited to 2 CPU's)

Nutanix discourages breaking the physical clusters into separate vSphere clusters, and also for resource management purposes I want to allow other VMs in the cluster to run on these hosts.

DRS affinity rules rely on VM groups that reference specific VMs, and I want to be able to manage these rule based on a search method (folder location, vm name, tag, etc.) in order to manage the hosts these agent run on so that the rules don't break when VMs are deleted/created by he Composer

Has anyone out there done this before, or have suggestions for how to proceed?

So far my only idea is creating a PowerCli script that runs occasionally to rebuild the DRS VM group(s), but it would be a significant amount of development and isn't an ideal solution (IMHO)

Other relevant details:

     VMware Horizon 7.11

     VSphere 6.5

Thanks in advance for your input.
