Options for hosting virtual machines on Ubuntu Server? (alien.top)

Hey folks,

I'm new to self-hosting and Linux, but I recently got a server up and running on some spare hardware that I had lying around. It's been a fun journey so far, and I have a few docker containers running things like AdGuard, Jellyfin, Portainer, etc.

I'm interested in trying out more Linux distributions like Arch and NixOS (all thanks to r/unixporn) and was wondering what my options are for hosting virtual machines on Ubuntu Server. They'll likely be for pure experimentation and light use, so I'm hoping to find a solution that would be easy to spin up or reconfigure frequently (maybe that's a non-issue and all virtual machines are flexible like this).

Could it be as simple as grabbing a docker image and running the VM inside a container?

I've also started reading about QEMU and KVM but wanted to get input before going down that route which seems pretty extensive.

Are there other options I should check out?

Also if there's a better sub to post this in, let me know

Thanks!

Proxmox if you want full fat versions of the OS and running programs inside them. Webtops if you just want a lightweight desktop of the OS that runs inside it's own docker container

Virt-manager makes qemu / kvm / libvirt pretty easy to use. It can also be used remotely over ssh (if you don't have a GUI on your server).

Proxmox all the way simply to set up great functions under the hood and in my experience much much easier\user friendly have QEMU and KVM

That's not how docker or VMs work.
