Could you provide an example of how to use the spice? I tried it myself
but ran into trouble of running an 'spice' agent (or whatever it is called).

I fear it is just my ignorance - as in *maybe* I was running QEMU
using spice but it was not clear to me if that was the case. Is there

that was because it wasn't compiled with that or I was doing something
