xenadmin VS Ganeti

Thanks. I looked at it briefly, but the project doesn't seem to be headed in a good direction.

The main interface (Xenadmin) now has an EOL notice as their README: https://github.com/xcp-ng/xenadmin

The other alternative now seems to be a paid solution:

That doesn't seem like a good match for my needs. :(

My only previous experience with a gui tool at that time was using the windows client which isn't very pretty (but, as it tends to be with software from my experience, even though it's ugly, it felt more responsive, and didn't need to be hosted, back when i had rather anemic hosts )

On a VM and have all the otherwise paid features like Backup. Works without any problems. Also you can use XCP-NG center https://github.com/xcp-ng/xenadmin on windows to manage your Hypervisor.

Just XCP-NG Center :). https://github.com/xcp-ng/xenadmin/releases/tag/v20.04.01.33

For clusters of VMs, there's things like Ganeti

There's also Ganeti. It works pretty well and has a long, stable, history of working well.

Ganeti will manage this.

It's funny, Google developed their own hyperconverged stack back in 2007 because it didn't want to give vmware any money. They had couple of engineers to build Ganeti rather than pay for all the vmware licenses they needed for corp office infra.

Maybe not "simple", but Ganeti is pretty powerful. A Ganeti + Ceph combo will build you a hyperconverged system. Ganeti will scale to hundreds to thousands of servers. Plus it can build multi-cluster setups, where you can move VMs between clusters easily.
