If you don't like vSphere (who does?) you can do all that in Proxmox.

Proxmox isn't quite there yet for scalibility and hyperconverged but it is getting there really fast. It's more of a competitor to Microsoft HyperV HCI.

Agreed. Its more reminiscent of Cloudstack or Openstack from what I gather. I'm thinking of Jetstream2, but for you buy it rather than rent some of it with an NSF budget.

Proxmox is nice and getting there but what you simply can't replicate is the lower level firmware and managing layer. Proxmox on commodity hardware will always be limited by that. Same goes for deep integration with the switch that Oxide can do.
