I have a pretty non-standard setup but with very standard tools. I didn't follow any specific guide. I have ZFS as the filesystem, for each VM a ZVOL or dataset + raw image and libvirt/ KVM on top. This can be done using e.g. Debian GNU/ Linux in a somewhat straight forward way. You can probably do something like it in WSL2 on Windows although that doesn't really sandbox stuff much or with Docker/ Podman or with VirtualBox.

If you want a dedicated virtual host, Proxmox seems to be pretty easy to install even for relative newcomers and it has a GUI that's decent for new people and seasoned admins as well.

For the remote connection I just use SSH and tmux, so I can comfortably detach and reattach without killing the tool that's running inside the terminal on the remote machine.

I hope this helps even though I didn't provide a step-by step guide.
