Please don't recommend Virtualizor, it has many bugs, code is outdated (PHP) and support team is lacking the technical skills. Also, it is not what OP is looking for.

For OP, in case your focus is on IaaS: I would recommend to set up a Proxmox cluster and do some testing, as it's free and is very flexible and stable too. It will satisfy your needs.
