VirtualBox is also a good option if you need a GUI for Windows for
example. I find it more performant than SPICE or VNC.

Qemu is an emulator. I don't think that is what you want, as it's quite
slow. Qemu is also has a set of useful tools.

What works well for me WRT KVM is virt-manager.

I only started using because Oracle effed up VirtualBox, but I'm happy
to report that I tried out VirtualBox again a few days ago to access
some of my old VMs, and the nonsense had disappeared in ascii at least.

I don't think you need Xen, but it is a good option. LXC is great for
isolating Linux. They have no overhead.
