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.
