VMs and VM management for your home

What do you use, prefer?

I have mostly used KVM with qemu, but I want to try out other things. I have heard of proxmox and all kinds of cool management things, what's a solid setup that supports easy backups and such things?

KVM and qemu is solid and pretty easy to understand. Basic control of the VMs can be done with virt-manager, which is a basic but solid tool.
