Is there a way to isolate VM deployments in the network? I would like to avoid any traffic between guest clusters/VM deployments. I see the IP pools and VM networks, but my servers have a few NICs and it does not seem scalable to separate them using separate cluster networks, VLANs seem like an option, but I'm not sure how scalable that one is as well, they would be on the same subnet. I've been trying virtual routers like vyOS and FRR router to try to further avoid a hardware router and keep everything virtualized, but it seems like a lot of complexity for something Kubernetes should be able to handle with namespacing. Is there a way to create a routable subnet within a Harverster cluster in an easy manner that can then be used for deploying a guest cluster within?
