You will record all sessions, all the time - not just when you have an
event or alarm, right?

Yes, there is a RFE upstream to record a spice session and the
last suggestion from Marc-André was to do that:

So, you plan to keep the session live with several VMs in order to
switch between them and also keep recording them. It could be
considerable amount of data.

The VMs are in a local network?

I always thought there should be a simpler way to record the display
with some gtk3 api/feature but I never look into it.. and to be honest,
a gstreamer plugin might give you a lot more flexibility.
