VM and Stack Deployment at Home

Without Installing another OS like Proxmox, does anyone know any tooling that will easily deploy VMs on my local computer and deploy software stacks on them?

I only have my desktop for hosting, but I also want to continue using it as my personal desktop.

I'd like to host game servers, cloud storage software, websites for clients. And have a portal for me (and potentially them) to be able to provision).

Edit: I'm just finding out about Apache Cloudstack which might do what I'm looking for.
